Hello ...
Well Long time ago I tried to explore the PSP (Playstation Portable) UMD videos, and I guess comparing their work on that matter with the recently Blu Ray structure. Relating that to the problem that I do have a lot of remuxed DVD with a huge file size that I can't play on PlayStation, I thought we might have a good solution here.

Is it possibe to Use MPEG2-PS containers to mux the video and multiple audio and subtitles (PSG) + menu navigation ... into 4GB vobs?
and hence by that we could have a DVD structure could be played on PS and also put on USB ...

UMD Movies, used AVC (video) + atrac3plus (audio) + png subpictures (as subtitles)

so any suggestion about that??
