I'm looking for a way to edit raw MPEG2 video on a Mac. Any ideas?

There was an article in the November issue (I think) of DV Magazine on deconstructing DVDs. In the article it, I thought it mentioned various tools for doing the job which included converting MPEG2 to DV for editing. I'm sorry but I left my copy on an airplane and I can't remember any of the details as I only skimmed it. You may be able to find the article on DV Magazine's website.

I don't know of anything that would allow you to edit MPEG-2 directly, you can get your DVD files to convert using this though:
