Does to job very well!
After my Hauppauge HD PVR broke for no reason I decided to purchase an alternative and I was not dissapointed. The AverMedia Game Capture HD does everything you want. It can take screenshots, record gameplay in High Definition. Extremely easy set-up. Remote control that came with it makes everything more pleasant. Saves the files in .avi format so it can be edited in almost every editing software. I use a 16GB USB to save the files and that suits me very well. Overall, very simple to use and does the job you want to a very good standard.
