I'm using a VIP722 with Over The Air Tuner and am in the Binghamton, NY DMA. We only get SD from the satellite here. The OTA tuner and outside antenna gives me just two locals, CBS and Fox, in HD. The other night I tried to watch a show recorded from my local PBS station, WSKG, and found I only had a black screen. The DVR was acting odd after I tried to view that recording. For instance the stop button would not clear the black screen. I had to play another recording, stop that, then I could get back to my normal menus. I assumed that was a one time fluke with that recording, but since then I've found every show I record from one of the three local channels I only get on the satellite (PBS, ABC and NBC) does that. Shows recorded from the OTA tuner record and play back normally and all other channels record normally. Is anyone else seeing this and does anyone have an idea what might be going on here?
