the vob files that i have are self contained movies that are originally in mkv format. Now since this thread is all about the PS3, and at the moment mkv files are not supported, i've takened the liberty to demux the mkv to vob, a format that the ps3 understands. Now, pls don't expect these files to play on your regular DVD players. I've tested it and even tried to burn it as a DVD ISO image or UDF, ayaw talaga. Our regular dvds don't have the proper codecs (H.264) to play it. Pero when you play these files sa PS3 connected to a receiver and a 1080p TV (even 720p), malinaw! Just like watching blu ray and hd dvd.
Also, there's no subtitle. I demux the files with no subtitle kasi di naman kaya i toggle ng ps3 so dinefault ko na lang sa off ang subtitles. Pag may mkv support na ang PS3, i'll give you mkv copies na where you can toggle the subtitles.
My player other than the PS3 is the mac mini. I use OSX Xbox Media Center. All files, ripped on 720p play on 1080p projectors and plasmas smoothly. Pls pm me with your concerns. The list naman is growing so i'll update you guys from time to time via pm
thanks
