It won't allow me to select 16:9 aspect ratio, only 4:3. It pops down like its going to let you choose but when you select 16:9 nothing happens, 4:3 stays highlighted. There's more problems than that (freezing up, poor performance) but I could live with that stuff if it would just let me choose 16:9 like I want to. I think I may have wasted 50 bucks. Any ideas?
