I'm editing about an hours of worth of video (.m2tc files) and everything was fine for a while. I slice, dice and delete portion of video I don't want. At about 30 minutes of video every time I hit Delete button to delete a clip that I don't need ,Vegas hangs and stops responding. At first I though it was my system being flaky (because it's old) so I moved the project to another newer machine and same thing is happening. FYI - when I move the clip to the end of the time line it works fine. Just can't delete. I checked the files to make sure they are not read/write. Any idea why this is?
