Will someone please recommend an easy way to cut/trim some video from a .mpg file? I got some files off my tivo, but there are 5 minutes of commercials at the end of each one which I would like to remove before encoding with the Turbo264 device. Any suggestions would be appreciated.

There's someone in my head but its not me...

Quicktime Pro allows easy cut/paste/copy in movies.

Download MPEG StreamClip... iMovie would require transcoding, QuickTime requires paying for Pro and again for MPEG2.

According to this site and Wikipedia, ".mpg" is MPEG-1 while ".mpv2" (aka ".m2p" or ".m2v")is MPEG-2 which would require the Apple MPEG-2 CODEC. Of course, it would make more sense to use MPEG-2.

Why not try opening the suspect .mpg file in QuickTime and see if it works? If not, then go for a free solution, otherwise get QuickTime Pro (which is very useful).

quicktime wouldn't open the files - gave me a "This file is not a movie file" error. iMovie also wouldnt accept it, stating that "quicktime could not parse it."

I'll check out MPEG StreamClip - but would paying for mpeg-2 and quicktime pro do the trick? would it let me edit out commercials from other files as well? thanks again

A tivo file has a tivo wrapper that must be removed before it can be edited. Check in the Tivo users board.

Which is nice in theory but does nothing to prevent people from putting MPEG2 content in an .mpg container.

Maybe, maybe not. QuickTime tends to be pretty brittle with regard to handling slightly nonstandard files, and the file from the TiVo may not be perfectly to spec.

Right, I thought MPEG-1 wouldn't make much sense and trust the extension would help identify it, maybe not though. I've had good luck with QuickTime Pro with many formats (using free third-party plug-ins), but an all-in-one, free solution may be best...at least worth trying first.

I've found that MPEG StreamClip handles many files that QuickTime Pro would choke on. I have and use both, for different applications.
I do not like those green links and spam.
