Windows XP Pro x64
MUST have 64 bit dribers! Any recommendations?
I've currently ordered PixelView PlayTV Ultra, will be using it for capture/input... to play playstation2 games. It's the only affordable card, that I know, that has 10-bit ADC, instead of 8-bit (for better quality of the capture). BUT there are no official x64 drivers for it, instead there's something called "DScaler" (google it) - that is an universal x64 driver for capture-cards (probably won't support the tuner).
Good luck, you'll need it.
