And to Carl's suggestion that we set the DVR to only 1080i output, I tried that... and I think there may be a bug there too. First, it still had the sync problems even though I was only going between stations that had the same res plus the DVR was set to output 1080p only.
I had all my resolutions UNchecked except 1080P on the HR22, but then if I pressed the res button on the remote, the HR22 would show 480p, or another non-1080 res... (my TV still saw it as 1080P as the Yamaha was upscaling.)
Seems like the HR22 doesn't change the output if you disable that resolution, and then you can't cycle out of it unless that resolution's button is checked.
Kind of maddening, and I haven't gone through the hassle yet to try to repeat it. I'm kind of in a 'make the best of a cruddy situation' mode right now and hoping DTV will eventually get this sorted with a stable release.
I have a similar setup with the DVR running into the RX-A3000, but a Sharp 70' Monitor. I also tried unchecking all resolutions except for 1080i and 1080p and the box does not up convert.
I also think from my diagnostics, that when handshake fails, the up-convert to 1080p in the Yamaha fails and it does a pass through on the signal. When the Yamaha can correctly identify the signal, it will up convert, and the graphics overlays are correct. Sometimes I get a picture to the Sharp monitor, but the graphics overlays are not correct. When this occurs I check the input to the Sharp and it is not 1080p(usually it is 720p on the HD channels). If the graphics are readable but squashed and off center, I check to see what the receiver thinks and it always thinks it is getting a 480p signal to up convert. To I think the receiver is incorrectly displaying the graphics because the signal is pass through, not up converted.
