Unlike Cisco TAs the Moto TAs don't have any specific diagnostics page to indicate which channels are SDV. However after some fooling around I came up with a reliable indirect method: There is an indirect way to find out if a channel is SDV with TiVo and Motorola Tuning adapter, but it's not very eloquent: 1. Tune to channel you want to check 2. Go to TiVo Central->Messages&Settings->Account&System Information->Tuning Adapter->DVR Diagnostics and note the Frequency associated with the channel you tuned to. 3. Left click out and then choose Tuning Adapter Diagnostics and then scroll down to DOWNSTREAM STATUS and click SELECT. If the INBAND FREQ listed on that screen matches the frequency you noted in step 2 then this is an SDV channel. The key is that the INBAND FREQ in DOWNSTREAM STATUS page only updates when tuning to an SDV channel. You will note for example if you tune to known non-SDV channels such as local broadcast channels that the INBAND FREQ will not update.
