I was watching "unplugged" on MTVHD, about half way through I hit the record button. When I went to play back the recording I got the following message:
"The TiVo HD was not able to record this program because there was no video signal on the channel."
I was watching the channel as it (supposedly) was being recorded.
My TiVo HD is only 2 weeks old. It is running the lastest TiVo software and using a MultiStream Cable Card from Comcast. Haven't had this happen before.
