Hi all, Tivo S3 w/cablecards installed. Odd thing began happening last night (before I did the 9.1 update, but it happened again after). Most, tho not all, my HD channels went back and silent. When I changed to an HD channel sometimes it said 'channel not available' or i got a black screen with no audio. The only variable I can point to was that I was using the online scheduling feature at Tivo. When I restart the Tivo it seems to correct it for a while, but it happened when the Tivo changed the channel to record a program on CW-HD. Did I miss this bug/issue somewhere?
