Advertisements I've received an replacement HD XL for my original one which had problems with the fan. The replacement Tivo works, records, and views shows, but also locks up. Twice now when I turned the TV on, the screen was pale gray. I had to power down & reboot each time. I've got OS 11.0K, that's the most recent I belive. My previous Tivo didn't have this issue. So either this OS is bad, or This tivo is flaky. Is anyone else having similar issues?
