Advertisements By this time, I'm ready to concede that anything is possible. However, if you go to the DVD diagnostics page (settings > Remote, CableCARD, Devices > Tuning Adapter > DVD Diagnostics), the box will display the status of each tuner, the CC and the TA. There is a line called "CableCARD association" for each tuner. My box shows that Tuners 0 and 1 are associated with "CableCARD 1", while tuners 2 thru 5 show "NONE" for CableCARD association. If you scroll down past the tuner 5 status entries, you will find the CC status and TA status ... in that order. One of the CC status entries is "Decrypt RecordChannels" my box shows the status as "2 (10)". I am uncertain what the "(10)" represents unless it is the binary equivalent for "2". I don't know if "Decrypt RecordCannels" is the same thing as "tuners" ... but that is what I am forced to conclude. Anyway, unless there is something inside the TiVo that does so, I don't see how the TA can affect how the CC resource is associated with the tuners. My TA communicates with the box via USB. My understanding is that TA is simply part of the SDV scheme. All that being said, I will next disconnect the TA tomorrow and see how the box responds.
