"It often arises that I have to edit MPEG files. This is a fairly difficult process in general but I have discovered a way to do it in QuickTime Player Pro. MPEG files are generated by EyeTV, ReplayTV, TiVo, and other TV capture devices. In general, when I want to edit one, I'm not so much interested in doing anything especially fancy. I just want to clip out the adverts and make a VideoCD or one of the related formats such as SVCD or CVD. There isn't a good MPEG editor available for the Mac yet, but with a little trickery you can get QuickTime Player Pro to perform this work for you. There is a GOP (Group-of-pictures) editor called GopChop that runs under X11, but I haven't managed to invest the time to get it going yet, although the developer's mailing list for it has been more than helpful.
