I have two Tivo units in service an elite 2TB and a Premier Standard which was upgraded to a 1 TB drive. On a reoccurring but infrequent basis (perhaps once a month roughly ) one or the other will seemingly stop receiving its cable feed, no error msg occurs but when you attempt to watch live TV on any channel the guide info is displayed but no audio or video signal, as a result scheduled recordings do not take place. A simple reboot of the tivo returns everything to normal. My suspicion is that this is a Cable Card Issue, wondering if others have experience this problem and if there is a fix for it..
My Cable Provider is TimeWarner..
