If the conditional access screen on the TiVo says... Con:No and Val:? Does that mean something is wrong with the card? If so is there anything that can be done to fix it from our end? Or does it have to be exchanged? I got my Sister a used HD. The first CableCARD we tried would not work. Just got stuck on a blue screen with spinning icon saying aquiring channels. I called the cabke company a couple of times, then hit it, hit the TA double checked all the pairing and SN values but it wouldn't work. Finally they said I needed to exchange it for another one. My Sister finally gets a chance to exchange the and I try installing it tonight but it has the exact same problem. Could this be something on our end? Bad TiVo? Bad TA? Or does that always mean the card is not validated correctly? What are the chances of getting two bad cards in a row? The weird part is I live right across the street and I have 3 Premiere units with the same exact cards and same provider and every one of them installed without a hitch. My Sister didn't really ask for this "upgrade" in the first place. I did it because I was trying to be nice, but I think she's getting fed up with the whole thing. Any help you could provide would be greatly appreciated.
