I don't recall my machines randomly rebooting. On occasion if I reboot my router, the Premiere and Premiere XL will lock up. It will turn on OK, but the minute I press the TiVo button to get my menu, the miniature screen goes in the right upper corner as usual, and the rest of the screen remains blue forever. It's like it's frozen. That's the only issue I've experienced. Recordings will still complete if they are in progress. The remedy was to pull the plug for a few seconds and plug back in. This only happened maybe once per month. I use antenna only. I have no cable. I wonder if these random reboots are happening to people who use cable cards? Maybe it's a hardware issue based on some odd signal coming from the cable company? I received the new version on one of my machines and haven't noticed a single thing different yet. Sometimes TiVo sends a TiVo message with their update so you can read what the update entails. I received no message with this update. I've only had it for 2 days. I may notice something in time. Maybe the monthly lockup after rebooting my router will be gone away.
