Advertisements I'm experiencing a wierd problem with my tivo hd. It has OTA and m-stream cable card installed on Cox Orange County Ca. Firmware is 9.2 All the correct channels display fine in the begining but over time I'll lose random channels (only cable not ota). They aren't part of a particular tier of premium or HD channels but a truely random selection. Some could be basic cable channels along with a mix of premium or HD channels. I can sometimes get a non-performing channel to display if I repeatedly change to that channel from a lower numbered channel. When I do a system reset all the channels work again for a day or two. Then I'll start the cycle over again with a random mix of channels not displaying any picture or sound. I don't know if its the m-card, some wierd cable issue, flaky firmware or a bad tivo unit. Has anyone out there experienced anything similar?
