Exactly. It's my style quick selection footage. I watch video samples in the Preview window while delete unnecessary material from the Timeline. I do not stop and play and stop and play....... I'll do more work in less time. In version Vegas 11 it was great. And it should work again.
I can replicate this error in VP12, 13 and 14 (build 201) using HDV clips. However I've never seen this in practice because I delete events using the DELETE command (programmed to one of my mouse's thumb buttons) rather than cutting them to the clipboard with CTRL+X.
The best way to get it fixed is to submit a support request via http://support.magix.com/vegas , including as much detailed information about the problem as you can.
