Advertisements I upgraded a Series 3 TiVo with a Antec hd enclosure and WD 750gb hard drive last night (successfully). System was off pretty much all day. I got home and noticed it was rebooting... It came up and gave me the following message: "The DVR has detected a serious problem and is now attempting to fix it. This will take about three hours. PLEASE DO NOT UNPLUG OR RESTART THE DVR! ....(plasma tv burn in warning). If, after three hours, the DVR does not restart, please call Customer Support." Has anyone else experienced this issue? Is this related to the upgrade or just a really timely coincidence?
