Ahh, there is a thing called an antenna, you mount it on your roof or in your attic and run a coax cable from it to your TV. You need to be within 50 miles of a transmitter. Then you can watch the Over The Air DH channels from CBS, NBC,ABC, etc.
As for the cables, try hooking the new cables to your DVD player an the TV. If this works then the problem is in the PS2, maybe you have to change a setting to use component cables. John
