Which of the two would you recommend, The ATI TV Wonder 650 or the Hauppauge HVR 1600 (or PVR 1600). I ditched my AIW. replaced with a ATI X1950XT so now need a tuner card. System is C2D 6400 @ 3.2 GHz, twin raid 0 - One with XP Pro, the other is Vista business. - Not sure if tuners work in Vista Business, most indicate Ultimate or Premium.
