ASUS A7N8X Deluxe
AMD XP 2800+
1GB Corsair PC3500
200GB Seagate HD
ATI 9700 Pro
Antec 550w PSU

I need a TV tuner card and I currently receive 3 OTA HD channels on my Sony XBR HD. Between the two cards which should I get? Because I am not sure which is better.

I briefly glanced at google... Seems that the PVR-500 is for MCE. What OS are you running?
