This is only occuring on HR20-100. No picture, no audio when first tune to WAAY-HD. Screen is completely gray. If I rewind, or pause, and then forward on dvr, HD picture & audio appears. If I leave channel and tune back, same problem. RBR makes no difference. Only on WAAY-HD (ABC). I have three other HR20-700 dvrs and this is not a problem on any channels.
Channels: 31 and 54

I have this EXACT same problem with 31 and 54, the HD channels, not the SD ones, on a HR20-100. This is sounding like a hardware problem - but maybe exposed because 31 and 54 are not broadcasting in 1080 ?
I had no problems with my older Phillips HD (tube) tv. Just replaced with a Vizio LCD 1080p, using same HDMI cable, and I immediately started having this problem. I find no other channels, local or not, that do this.
I found the same work-around (actually found it by using the new swap function which works too since it is buffering), rewind until a picture then ffwd back to live TV and it works, until I change the channel to a channel with higher resolution. Then if I return to 31 or 54 I have to do the work-around again.
I tried disabling every resolution, just selecting one, and worked through the whole list, and nothing helped.
I do notice 31 and 54 are the only locals showing on my Vizio as a 720p source, the others show 1080i (even when I set the DTV box to 1080p only.)
I knew something was strange when I had a blank screen on 31, reset the box, and when it rebooted I had a picture, until I changed the channel and came back. Had DirecTV on the phone when that happened and they still said it must be the local channels not broadcasting their HD signal at the moment.
