Yes.
But currently, analog channels (which is what the DVR channel would come in as) just look a little off.
You might also consider using a composite (yellow, red, white RCA cable) connection from the DVR to one of the two 811 composite INPUTS. They will show up in the 811 guide as 000-1 and 000-2. I haven't done this, but I've read that that the quality doens't look that great, either. But you would still have the OTA ANTENNA INPUT available for your regular OTA analog/digital channels.
