depends on:
a. what inputs the tv tuner card has
b. what outputs you have for the PS2
ie. If you have a PS2 with the RCA (red, white, yellow) AV cable, but your TV Tuner card only has a standard aerial (COAX) input, then you'll be SOL, unless you get one of those third party COAX av cables. Mine was like $20 from the warehouse, but I dont use it coz the old telly died and the new one has RCA inputs
