Review your channel list to make sure all the channels you subscribe to are marked with a yellow check. Compare the channel list to the list of channels in your cable plan.
The TiVo DVR requires a CableCARD™ decoder to receive any cable programming. Contact Wave Technical Support to make sure that all of the channels in your cable subscription have been activated on the CableCARD decoder.
You may be trying to access an antenna or analog cable channel. The TiVo DVR or your TiVo Mini* does not receive analog channels.
