That's going to depend on Service Electric Cable TV. I the room without the set top box, you'll only get those channels they send unencrypted. In the room with the set top box and the output from the set top box going to the input of the TV Tuner card, you'll get all the channels you subscribe to (but you'll have to use the set top box as the tuner since it does all the decryption).
Thanks for your reply. So how do I know what channels are encrypted by my cable provider? Call them? Or do I buy the tuner card, hook it up and see what I get. Then hope for a good return policy
