Does anybody else get this error on TBS ? I'm on COMCAST, Miami and I have a Roamio Plus. I'm using a CableCard that was installed on a previous Tivo with no issue at all. After transferring and activating the card on the new Tivo all channels work as expected except TBSHD (421). You can watch this channel sometimes, but when it returns from commercial breaks the screen goes blank and the v53 error appears. I've tried changing channels, changing to a SD channel and back and nothing. The problem autocorrects itself after a while as long as the channel is not tuned. When you start watching the channel again after a whiles it does it again. Any suggestions ? (I have tried with two different Tivo boxes, and two different CableCards, same result) Thanks !
