[Scott Witthaus]"Have fun with Premiere and watching it crash."
Funny, I had FCPX crash on me twice today when I was trying to add a simple dissolve between two clips on a straight timeline (no FX or anything funky). The second time took OSX with it, causing a hard reset.
Never had it crash on AVCHD so I wouldn't know. All I felt was that Premiere was struggling and was always on the edge. Like your X problem, it could have been the system I was on (a clients, not mine). To each his/he own.
