Disguising MPEG2 video as MPEG4? [Archive]

I'm not sure if this is the right section to post in, but none of the others seem to fit either...

I have a Samsung Series 7 TV which can play all sorts of media. I've ripped DVDs to .vob/.mpg in the past, but find that the TV has trouble with seeking after a certain time in the file.

I've just tried mkvmerge to wrap the MPEG2 video and AC3 audio in a .mkv container, but this is a format the TV doesn't accept (it will however accept MPEG4, H264, etc in .mkv).

My question is: is there a way to disguise the MPEG2 video as MPEG4, i.e. is MPEG4 a superset of MPEG2? That way I'd be able to make a .mkv that the TV could understand without reencoding.

Can you post the specifications of the TV's media player? ie what file formats and any further details that might be included like bit rates etc. This would help.

I don't have specifications as such, just a list of containers and formats in those containers that it will play. It will only play MPEG-2 video in a .mpg, .vob, or .ts container, and I know it has seeking problems with .mpg and .vob, and won't play AC3 from a .ts container.

It will, however, play MPEG4 (SP and ASP) and AC3 in a .mkv, .avi, or .asf container.

How about this: Rip your VOBs in IFO mode with video and audio demuxed. Then mux them back using VOB Blanker.

I'll give that a try - maybe the seeking problems are down to the difference between the separated VOBs on the DVD, and the joined one (however that's made) created by the ripper...

Have you tried generating .M2TS muxes? Perhaps the Samsung prefers transport streams with 192 byte packets instead of 188 byte packets...
