What settings are you guys using with your successes? I just tried to recording sessions and both of them failed. One stopped around the 30 minute marker, and the other failed after 18 minutes. Also, what are you specs in general?
Also, how long were you recording?
Edit Update: I'm still testing various things, the problems seem to occur when you record with the Active Desktop Region. Recording active screen seems to work fine. It might be worth looking into the Active Desktop Portion to see if there's something different about it.
Edit update again: Although even without a Active Desktop Portion, it still seems to crash without warning when pressing the button to stop it, and then immediately following up with a recording. I wish the program would just give a message or SOMETHING to help with this.
