H.264 in MPEG-2 container?

[F-Man]

Hey, I have some video files using the H.264 codec and an .mpg extension. According to MediaCoder, they're in an MPEG-2 container, and needless to say, not many players seem to support said files (from Winamp to WMP to even VLC), only one I could get to work so far is Media Player Classic.

Anyway, I was wondering how I could convert them to another container such as AVI to make them more... playable. VirtualDub say "MPEG Import Filter: invalid pack at position 3: maker bit not set; possibly MPEG-2 stream.", VirtualDubMod crashes and MediaCoder doesn't seem to support the input file (and also crashed before I updated it to the very latest build).

What shall I do?

avc in mpeg ps/ts is better than in avi. try mplayer to extract raw streams and mux to mp4 or mkv with YAMB or mkvmerge respectively.

mplayer doesn't seem to be able to play the video as well.

I get this:

Too many audio packets in the buffer: <4096 in 8273920 bytes>.
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
MPEG: FATAL: EOF while searching for sequence header.
Video: Cannot read properties.
