I am also having the issue of constant crashing. I am using Mac OS 10.8 with Intel dual core processor. If I run it on high quality, it crashes in less than 10 minutes. If I run it on medium, it'll go for a while longer. However, I don't get any picture in the playback window so all it's recording is a green screen with no sound. I'm still trying to troubleshoot that one too. So far I've gotten NO help from Roxio support. What a major waste of money and time.
