My TiVo Premiere has been acting flaky today. First, while watching Hulu, the screen goes black and then I see the welcome video. Second, while watching Netflix, the screen goes black and I'm sent back to My Recordings page. At this point, I did a manual reboot. Third, while finishing the movie on Netflix, the screen goes black and then the TiVo reboots on its own. Any ideas as to what is causing this? Before I did the manual reboot, I noticed that I was running SW version 14.8U(something).
