Just bought the ATI - TV Wonder and..
I love it...but it is kind of buggy. If you aren't extremly careful the TV display will get stuck in the NTSC display mode..and nothing you do will change it to NTSC-j.
It is annoying, but playing vhs and mario on the computer is pretty cool!
I really want to get a cable line up here...take a little effort though.
(Does anyone know why I can't record very good. It occassionally flickers making it unsuitable for transfer to DVD. I've set the proccess to high priority but to no avail. :( Maybe you can record without the display on??)
