Topic: A very weird playback problem...

[reynold]

Good Day fellow members,

I need some inputs/advice from you guys re my weird problem. Hindi ko talaga mahuli kung ano ang problem e...

Here's my equipment:
Panasonic 42PV80
Yamaha DSP-A1
Sony and Wharfdale Speakers
Mede8er with bnew internal hard disk (320gig Seagate)


Here's the problem...
Crackling Sounds (nanginginig or garalgal) during .m2ts playback only...
Other files like mkv, mp3, m4a, etc... OK naman.


Here's what i did to isolate the problem... (testing same files)

1. Changed the Optical cable with other optical cable ganun pa din.
2. Changed the optical cable with 2 diff coax, ganun pa din... so wala sa mga cables ang problem kasi ok naman pag ibang files... i doubt sa receiver or speakers ang sira kasi ok din naman ang ibang files...

3. I called eHome, they asked me to bring my mede8er (that time, v2.1.1 ang fw version nya) kasi baka yung unit ang may problem (maybe board, maybe FW...)

4. So they told me na i-try namin palitan ng board yung mede8er, so pinalitan nila, waited for almost 10 minutes then after that we did some testing... Nawala ang garalgal, umayos... so sabi nila board nga siguro, pero eto ang weird... Since umayos na yung audio playback, yun na lang daw ang gamitin ko pero policy ng company na i-test muna daw yung ni-replace na board, so binalik ulit nila yung board at ng tinest namin, ayus pa din ang audio playback at walang garalgal, ilang beses ko pinaulit-ulit na test pero ok talaga... and since wala naman pala problem yung dating board, pinabalik ko na lang ulit and then test na naman... Ok pa rin... Weird...

5. Baka Firmware naman, so pina-upgrade ko na ang FW sa kanila to v 3.0.4 then test ulit, so far so good... so sabi ko, test ko na lang ulit sa bahay yung unit para makita ko ang effect ng bagong FW...

6. Sa Bahay... Setup... Test... and then tadddaaaammmm!!!! ganun pa din ang audio, garalgal na naman


Hindi Cable... Hindi rin Receiver or Speakers... at lalong hindi din Mede8er ang problem kasi ok nung nakasalang sa setup sa eHome e, hindi rin file kasi ok din ang test nya pagdating sa shop... Ano kaya ang problem


Baka meron kayong same issue na ganito kahit ibang brand ng nmt, share nyo naman dito sa thread na 'to, especially mga solutions na ginawa ninyo...



Thanks,
Reynold

isa na lang ang di mo nasasabi... bahay!

yes, sa eHome ka na tumira  teka paupuin mo naman ako sa lazyboy ha  jk

[reynold]

Matanong nga si Richie kung pwedeng tumira sa shop nya, hehehe

[batanglambak]

nung dinala mo yung mede8er sa ehome .. tinest niyo ba muna bago pinalitan yung board? ... naisip ko lang na baka okay pala talaga kaya nung pinalitan ng board ay walang garalgal ... kung sakali, maa-isolate natin kung san talaga ang may problema .. kung ang setup sa bahay o hinde ...

may mga .m2ts files din kase na may garalgal sa akin using my wdtv at my xtreamer .. akala ko nga dati sa wdtv ang problema kaya bumili ako ng xtreamer thinking na maayos .. pero nung play ko sa xtreamer ay ganun pa din .. may garalgal ... playback sa pc ay okay naman ... yung .m2ts files ay yung mga 1080p encoded for ps3 ...

judging from your setup, sa isang gamit lang tayo pareho ... sa yamaha dsp-a1 ... dun kaya ang problema ng garalgal?

i have since deleted the .m2ts files kaya di ko na matetest .. di ko rin natest kung okay ang sound ng direct sa lcd ...

[reynold]

Thanks for the reply bro

Yes, tinest din namin yung board ng unit ko noon, ok naman at walang garalgal bro...

Here's what i have in mind, i don't know if its possible... since pareho tayo ng receiver, hindi kaya nahihirapan ang receiver natin na i-decode kung anuman ang audio format ng mga m2ts files? is it possible kaya? pag other files naman ok like mkv, mp3, etc e, dun sa m2ts lang sablay e...

[praktikal]

upgrade receiver na yan! 

[Clondalkin]

Naisip ko rin ang DSP-A1.

However, my DSP-AX1 has no problem whatsoever with pure BD rips and BD ISOs     Ang ganda nga ng tunog kahit na DTS or DD lang ang kaya nyang palabasin from DTSHDMA or Dolby TrueHD sources respectively - pero baka yon ang "X" factor sa model number? 

What's the exact file?    m2ts demos or full length films or concerts? 

[markcrenz]

akala ko sa gallery lang may kulaman!

ngaykzz!!! 

here's my story. medyo ot:

nanalo ako ng gas range nung minsang party namin, kaso wala akong mapaglagyan. ano ang nangyari? ang dating dirty kitchen pinabubunga, inayos, nilagyan ng tiles at ginawang totoong kitchen. ng dahil sa gas range yan ha  higit pa sa presyo ng napanalunan ang ginastos sa maliit na kitchen. after 2 years nanalo uli ako ng 2 burner stove lang worth less 1k lang ata yun, shet! walang mapaglagyan! ano ang nangyari, nagpagawa kami ng concrete stand para lang dun para 2 ang kalan. again, mas mahal pa sa napanalunan ang ginastos -- again. 

ito ang matindi. pinabubungan namin ang suppose to be na garahe para di lumutin ang sahig at magamit na rin tuwing may handaan... ano ang nangyari next? 

now back to topic: ng dahil sa m2ts, may bagong receiver! yahooo!!!!

It's a full-length movie sir, ang hindi ko lang alam at mahuli ay kung ano ang pinagkaiba ng audio format ng m2ts sa mkv at bakit di kinakaya ng dsp-a1 (kung yun nga talaga ang problem)...

This weekend pag-aaralan ko ang specs ng DSP-A1 (lalo na yung chipset na gamit nya kung ano ang audio na supported nya), sana nga maintindihan ko, hehehe

Nakupo, ikaw pala ang malakas mangkulam e, hehehe
Magkano na ba ang receiver ngayon? Ano kaya mga pwede kong ibenta?? mailista nga this weekend

[ǝʞɐɾ ʎzzɐɾ]

sir reynold, puwede na pong palitan ang title... "looking for AVR replacement"

hehe!  joke lang po...

anyway sir, have you tried playing mt2s with another NMT?

[reynold]

hahaha, Sir Jazzy Jake wala pang budget, maghahanap pa ng makukuhanan (lumang-damit palit ng bnew AVR, meron ba?)

Yan ang hindi ko pa nagagawa, wala na kasi akong ibang nmt e... i'll ask my officemate kung may problem sa kanya yung mga m2ts files nya, sa kanya ko kasi kinopya yun e, he's using wdtv, kaso nasa meeting pa sya ngayon e

Hindi kaya dahil dito?

Yamaha DSP-A1:
           24-Bit Processing Dolby Digital LSI (YSS-249) and DSP LSI (YSS-214)

Yamaha AX1:
           44-Bit CINEMA DSP LSIs (Yamaha Original YSS-910 x 2)
           Original YSS-918 and YSS-908 LSIs


What do you think sir?

[av_phile1]

This seemed like deja vu from another poster in the past.  It was the DSP-A1 processor that was at fault.  It could not process high definition audio since it was a 2003/4 model.  

m2ts files are container files for BD content.  Ergo, you can't decode those lossless audio content with pre-2007 gears but their DTS and DD tacks can be decoded.

But even their DD and DTS content are encoded at a higher sampling rate, so not all DD/DTS decoders can. 

mkv files are ripped BD files whose audio content are mostly transcoded to lower resolution DTS or DD files so they have lower file sizes.

So sir Av_phile1, you are saying that this is really the reason why i am having issue on m2ts audio playback? Nakupo, wala pa akong pambili ng bagong receiver

Is there a solution ba for this without buying a new receiver, like converting m2ts to mkv (w/c im not sure if there will be some quality impact on video and audio), or delete all my m2ts and replace them with mkv movies, etc.?

btw, i think DSP-A1 is a 2000 model

[scifi-fan]

m2ts containers can have HD Audio and standard DD/DTS audio tracks.

Kelangan himayin yung m2ts files mo using a program called mediainfo to confirm what audio tracks are inside, sometimes they could have weird sampling that causes the issue you describe. 48Khz is normal sampling for movie audio tracks. Some "junk" encodes use 44Khz sampling which the player can't decode properly.

DTS-HD audio tracks normally have a core DTS inside them. Dolby TrueHD tracks require a separate AC3 track for non HD audio receivers.

in addition to mediainfo...

ts muxer can also be used in identifying tracks inside m2ts/ts files which also describes details such as track type, sampling etc.  ts muxer can convert/remux DTS-HD to DTS and Dolby TrueHD to Dobly/AC3 for non HD audio receivers.

[Clondalkin]

What's the exact filename?

[Gwenael]

sir reynold,

sinubukan mo na bang mag cycle dun sa audio tracks nung file na pinapanood by pressing audio on the remote of mede8er mo baka sakaling pwedeng DD or DTS audio track palabasin instead na HD audio?

^^^
Usually iisa lang ang audio tracks ng mga files ko sir Gwenael, it only shows "6-Channel DOLBY Digital"... but the weird part is... some shows 6-Channel DTS pero garalgal pa din yung audio...

Sir Scifi-fan, i'll try the mediainfo and ts muxer... madali lang ba gamitin 'to? do you have a copy of these tools? Thanks

[reynold]

...done with the downloading of mediainfo and TS Muxer mga sir, papaano ba gamitin ang TS Muxer? pwede ko ba palitan ang audio codec ng isang m2ts file using the TS Muxer? Thanks

[scifi-fan]

what you want to try with tsmuxer is to convert the m2ts files into either BDMV folder structures (original Bluray) or AVCHD.

Don't transcode the audio to another format until you're sure it's that causing your issues.

yes, you may remux your m2ts file into another m2ts file with new audio codec (Dolby TrueHD to Dolby/AC3).
when you open your m2ts file you will see the tracks on it (video, audio, subtitles).
if you want to change audio coded (e.g. Dolby TrueHD to Dolby/AC3) select on that track and you will notice downgrade to Dolby/AC3 in the lower portion after the track list
you may also unselect tracks you want by deselecting (uncheck) it from the list
make sure you selected m2ts as output file and then press remux

Thanks a lot sir eksi, will try it later at home

Thanks a lot sir eksi, will try it later at home

no problem sir, glad to help

[batanglambak]

may mga .mkv files din na gumagaralgal tulad nung .m2ts files .. napansin ko lang na sa tsmuxer ... nakalagay na 6 channels yung sound .. pero pag 5.1 channels ay okay naman ang playback ... diyan kaya ang problema ng yamaha dsp-a1?

natest ko din yung .mkv file sa wdtv - logitech z5500 at okay naman ang playback ... sa xtreamer - yamaha dsp-a1 lang talaga may problema kaya sa tingin ko yamaha dsp-a1 talaga ang culprit.

ano kaya magandang receiver ang ipalit sa yamaha dsp-a1? kahit sana low budget lang basta capable na ng trueHD.

thanks.

[praktikal]

i will stand firm on this...

Yup, sa receiver nga natin ang culprit bro, old skul kasi e, hehehe pero di ko pa rin ipagpapalit DSP-A1 ko sa iba


Amigong praktikal,

wala pa kasi ako budget para sa TRUEHD na receiver kaya convert-convert na lang muna ako ng m2ts to mkv, yan ang pinaka-Praktikal na paraan sa ngayon

[sillyputty]

Wala bang NMT na may 8channel analog out? 
old school din kasi receiver ko pero meron syang 7.1 input.

now, you're talking just like me 

i owned a dsp-a1 before i upgraded to 659. ang ganda ng itsura at tunog. just wanted to experience more than this a1 can offer. 7.1 that is pero actually, 6.1 lang ang setup ko ngayon. gaano man kaganda since meron namang affordable preowned new models, so why not coconut.
