Advertisements I have a new Tivo HD with Comcast. They've tried multiple Motorola M-Cards with my Tivo, and everyone can not get the encrpted channels (I only get locals and HD locals). Under the conditional access screen when it is tuned to a channel that is encrypted (USA or TNT for example), for Val: it says V 0x00 (so the card seems to paired correctly), but for Auth: it says MP where it should have an 'S' (for subscribed). So from everything I've read, the card is not authenticated (this was the case for 4 different M cards). I've talked to many Comcast 'techs' on the phone. They said they've sent out every activation signal and 'hit' they could, and nothing has worked. They said the card is paired correctly and activated in the system. So my question: Has anyone had Auth: MP in the conditional access screen (and only received unencrypted channels)? HAS ANYONE HAD THIS PROBLEM FIXED? HOW DID YOU FIX IT?
