I still use Vegas 7 and will not upgrade it (although I can get it under 150$) untill AVCHD is fixed. The problem is that I already have so much staf made with my sr-11 camera that I started thinking of how Cineform would work with Vegas 7 to process AVCHD?
Out of interest, what AVCHD issues are you referring to?
As I'm tempted by the current upgrade offer, I've been playing (albeit briefly) with the trial version of 9.0c and from my point of view it seems better - at least I can render back to AVCHD - 8.0 always crashes on me!
