According to this thread: http://forums.support.roxio.com/topic/120254-crash-when-click-stop-capture/
I was advised to stop capturing to mp4 file. Allright, I changed it to mt2s, but there's a teeny problem. It does not have any sound! The videos is useless! I now have to replay most of a game for new videos that I can actually use - but first I need to solve this problem. Running win 10 laptop, i5 core, nvidia graphics card. What am I doing wrong? And if you tell me it's just a bug happening from time to time, I'm down to frikking luck if I get a video I can use?
