Topic: DVD -r & +r ??? whats the diff?

[jlodvo]

ano pagkaiba nila?

[idlewild]

you can read more about it here.  there's really no big difference between the two formats.  personally, i mostly use DVD+R for two reasons: (1) bitsetting capability, and (2) better write quality on this media (meaning, my drive burns +R better than -R)

There's actually a big difference.

I started with +R because I was impressed with this technical article (kahit hindi ko naintindihan) entitled "Why DVD+R(W) is superior to DVD-R(W)", June 2003, by Michael Spath: http://www.cdfreaks.com/article/113     

---------------------------------------------

My personal views:

After about 70 burns, I now use only DVD-R for the following reasons:

1. Compatibility: +R has higher compatibility with writers, but -R has higher compatibility with standalone players.

All +R blanks I've tried are compatible with my Lite-on writer, but some of them are incompatible with older standalone players, even if set to ROM booktype.  Naniwala rin ako sa sinasabi nila tungkol sa high compatibility ng +R or +RW with ROM booktype bit setting, pero from my experience, hindi pala totoo.   

Many -R blanks are incompatible with my Lite-on writer.  But in the instances where the -R disc is compatible with my writer, the burned -R disc always plays perfectly in all of the standalone players I've tried. (The oldest player I've tested is a 2001 model)     

2.  Scratches on disc:  +R discs get scratched by the drive.

Out of around 70 discs successfully burned, 5 of my +R discs were scratched by my Lite-on drive and both of my Pioneer players.  It's a deep scratch, perfectly concentric, usually about 3 inches long. 

I've asked several people to explain it, but only one of them gave me a reasonable explanation.  He theorizes that the scratch is caused when the disc's spin is not level.  A momentary wobble on a spinning disc, even for a fraction of a second, causes a portion of the disc surface to come into contact with an internal part of the drive, thereby causing the scratch.

This has never happened on any of my -R discs.

bottom line is go - R

correct?

For video, use -R;  for other data, use +R.

It could simply be a problem with the brand of -R discs that you purchased.  I use generic DVD+Rs and DVD-Rs from CD-R King and I hardly encounter problems using my DVD writer. 

However, while they all play on my optical drives, some discs do not play on some of my friends' DVD players.  But it's just a matter of knowing whether a particular DVD player is compatible +R or -R.  Newer DVD players should have not have any problems playing either format.

True.  Compatibility lang siguro ang problema sa +R ko.

Yung scratches nangyari sa Sigma +R and Imation +R, both made by CMC.

Minsan naman, binigyan ko ang pinsan ko ng isang burned DVD movie on a Ridata +R.  Perfect results on Nero read test, pero nag-hang sa player niya.  Napahiya tuloy ako.  Medyo luma na kasi ang player niya (Pioneer, year 2002). 

Pag -R ang disc, laging OK, kahit luma na ang player.

Hmmm... interesting.  Both DVD-Rs are ok with my writer and player.  But I don't buy moon and stars anymore coz it just looks awful.
