I'm not an expert, although I did start recording my gameplay a few weeks back, and more dedicated recording a few days back. Key points are: - Properly set up recording program (Fraps doesn't take a lot of settings, it eats ram; try Dxtory, it's complicated but very good.) - Use a different hard disk with enough space. If you use the same HDD it has to read and write too much on the same disk and that will cost you. Also make sure you don't record to a USB HDD (external). They're slow as hell. http://dxtory.com/v2-home-en.html - Dxtory
YouTube setup video (I don't know if this is the one I used, but you really want a good explanation, try looking around a bit) Keep in mind that you eat space quite rapidly. I record 30fps and 75% screen size with the H.264 codec on like 10min/GB I think. Let me know if that helped. EDIT: Follow the guide SIMJEDI posted, it's probably better.
