I have been having awful problems with Series 2 - can't find one tuner or won't change channels. TIVO now tells me that they can't use a dual tuner with fully digital cable. They told me they are working on a fix with no anticipated timeframe it but it does not work currently. I can't find anything in the forums on this. Comcast knows nothing about this - has anyone else heard anything about it?

I am so frustratd my tivo box is only a couple months old.

Thank you
