Advertisements System is around 2 months old. TiVo Series 3 HD hooked up via HDMI and using a Cablevision Multi Cable Card. System has frozen 5 times in last week. 3 of the freezes happened when I pressed the TIVO button and it froze at the Now Playing screen. (The screen showed no recordings even though there were 10 or so). Waited 15 minutes and did not recover and had to power cycle. The last 2 times the system frozen upon changing channels. After a minute or so of waiting the system rebooted by itself. Any ideas?
