I think I might be having a similar issue. For the past 3 sundays, Sunday Night Football (SNF) has not recorded. It is scheduled to record at 5:30 PT, and at 5:29 it did show in the "todo" list. But the recording never shows up, and when I try to tune the channel via the guide, I get a black screen (but the play bar acts like it is tuned to channel 805, a music channel). After a reboot, the recording starts.
What is even stranger to me is that by week #3 I had set my other PVR, an HR24, to record SNF also, and it did not show up there either. But the channel was tunable manually from the guide, so I tuned to it, and started a recording manually.
Also, it is worth mentioning that SNF is one of six manual recordings that I am doing (all NFL football) but there are little to no conflicts at the recording time. Maybe one or two other shows, tops. SNF was #6 in my series recordings priority during weeks 1 and 2, but by week 3 I popped it up to the top (hoping against hope that it would just record).
Is there any way I can get this info to D* without being a part of the cutting edge program (I like to stay away from the bleeding edge when at home).
Thanks in advance.
