Can anybody tell me if QT Pro allows you to open and trim .m4v files without a problem? I have Toast 8 and it converts programs I've pulled off of my Tivo into .m4v files, which is fine, but I was hoping I'd be able to trim off the misc. commercials at the beginning and end of a program so I don't have to watch that on my iphone also. I'm sure I can't remove the commercials in between, but if I can at least just cut the junk from before and after the show that would be nice. Another option might be to convert the movie into .mp4 so that I could edit it in iMovie. Does QT Pro have the ability to re-encode from .m4v to .mp4? Thanks!
