I downloaded the trial version and it does great. It only records 45 seconds of video until it's registered, and you can't make any changes to quality and other features, but I was impressed with it so far.

Since WOW is down for maintenance, I recorded two different videos of me playing Titan Quest - Immortal Throne and the quality was great. Even when I changed it to view in full screen it wasn't too bad.

The 45 second videos were 100mb each which seems about right when recording this type of video.

Thanks for pointing me to this product!
