Yes, I used the newest version, it did not help.

Hmm...Cineform has sent me the update attached to email since I had previously filed a support form, but that was for their trial version which has long expired, so the update they sent does me no good. But...lately I've been having Vegas 7e crash on me when auto-previewing .m2t files in the Project Media folder. It's super annoying since I don't know when it will happen, so I think today I may just shell out the cash and get NeoHDV thinking that using the Cineform intermediates may not cause Vegas to crash when auto-previewing clips as I've been doing. I'm going to test this with some of the Cineform files I had captured during the trial period and see if auto-preview remains stable in Vegas.
