The problem as I see it: This channel is temporarily unavailable. Press select to try tuning to this channel again. Contact your cable provider for more information. My equipment: TiVo HD, with one multi-stream cable card. 3 years old Cisco STA1520 Tuning adapter. 1 year old My service: Cox San Diego South Cox Advanced TV Pretty much all channels they offer but NO premiums (HBO, Showtime etc...) I get the above message when I'm surfing channels 100 and above. And I do surf a lot! It's not always the same channel. I can be watching it one minute, continue surfing, tune back and it's gone. Also, I'll be watching a particular channel for an extended period of time and it will just freeze. Sometimes I can tune away from it, tune back and the problem is solved. But not very often. Recorded programs never affected. Mostly network stuff. Never in HD. I apologize if this issue has been addressed in the past. Just couldn't find it directly relating to my issue. What's going on? TiVo? Tuning adapter? Cable Card? Cox? Operator error?
