On my Tivo Premiere with upgraded hard drive and multi-stream cable card, I am having the following problem: * While watching a show, the audio (not video) cuts out for 1-2 seconds. Today it happened at 30 minutes past the hour, and I believe it happened another time on the hour. I believe it has been happening for a month or longer. I did request and receive the beta software around the 12th, and today with the new software it happened again. Has anyone else had this problem? Could it be a bad or failing hard drive? One idea is that it could be due to a recording starting or stopping on one of the tuners but not necessarily the tuner I am watching.
