Advertisements I have a TiVo HD which was upgraded to a 500gb drive last week using winmfs beta 5. I did an mfscopy. The upgrade was completed one day before software version C was automatically downloaded. I am on Cablevision of Long Island with NDS Cards. On two separate occasions, the unit has blacked out. The first time I was changing the video setting from native to 1080i and when I hit the Live TV button, the screen was just black. It did not tune to anything. If I hit the TiVo button, the menu came up, but there was no background - just black. The same thing happend on another instance when I was doing a wishlist search. Once I was done with the search, i hit live tv and the same thing happenend. The only way I could figure out to remedy the problem was to restart the system and rerun guided setup (but of course the cable cards did not initiate properly on reboot, so I needed to remove them and reinsert them). Has anyone else experienced this problem? Is it because I upgraded the drive or is it the new C software version? or just a bug that I coincidentally found 2x this wekeend.
