I'm sorry if the topics has already appeared elsewhere. I searched but didn't find any mentions. I have a 722 and it has worked well for me for 3 or 4 months. Two days ago (the debate was the first time I noticed this) I started having a problem. On two HD channels (local Fox and NBC) I can no longer record. I can watch the channels live, but if I pause the channel it skips forward to the live broadcast when I hit the play button. If record something on the two channels there is a file that says it is 30 minutes long (or whatever the length of the show), but if I play the recording it says it has reached the end of playback. The two channels work fine in SD and my other HD channels (including local ones) seem to be fine. I haven't made any recent changes in the system. Things I have done: I unplugged the DVR for a few minutes, I have a signal strength of 73, I did check switch, System Info gets Status: Good. Thank you for you help.
