As the saying goes, Trust, but Verify......
I went upstairs to my 4311, verified that the DirecTV box is outputting in Native Mode, and went to the video signal information screen in the 4311. I then tuned to Fox, and the 4311 display shows 720p=>1080p. I then tuned to NBC, and the 4311 display shows 1080i=>1080p. I ran the same test, but using the status display on my Sony monitor. For both Fox and NBC, the Sony status displayed 1080p.
So, as I said in my previous note, I am not experiencing the same issue as you are, which tells me that the issue may not be caused by the 4311, but rather something else like an HDMI handshake issue.
As a side note, I notice that the video signal from my upstairs HR21 DVR is displaying as YCbCr 4:4:4 => YCbCr 4:4:4, while the signal from my downstairs HR24, through the 4520, is showing RGB 4:4:4 => RGB 4:4:4. I'm not aware of any setting in the DirecTV DVR's that allows selection of YCbCr Vs. RGB. Strange...
Edit: Just read that the HR24-500 outputs an RGB signal, unlike the other DTV DVR's.Edited by AustinJerry - 1/4/13 at 6:11pm
