I have an MPG clip that won't play in Media Player, error "Cannot play back the file. The format is not supported.". TMPGEnc won't load it,
error "unsupported".

BUT

PowerDVD will play it.

The clip is a music video and starts well into the song. That leads me
to suspect that maybe the clip has had its header chopped off. I'd like
to save the song, can anyone suggest a way to recover the usable
video?

Thanks!
