Hmm, good to know. Might have to revisit FCPX. I tried it a few times and finally abandoned ship because I just felt like I was editing on iMovie. I have Premiere Pro CS 5, but it deals with h.264 as poorly as FCP 7. Switching cameras would be a solution for me, but I often edit for other people, too, and mostly the footage comes from DSLRs.
