This stinks I was hoping there was a set up thing I could do. I'm calling today.
I do not have the same model Samsung or DirecTV receiver as you, but I suspect this might be your problem.
If you did not have the Samsung at the time the HR20 was installed, there is a good chance that the HR20 was set to only output 480p during initial setup.
On the HR10-250 D* receiver that I have, you need to go to "Settings", "Video" to select the output formats that the box should support. I assume that there should be something similar on the HR20.
Whichever format is chosen, all video signals are converted to that format for output from the box.
Also, my Samsung HL-R4667W has a menu key that allows you to select which video format to show.
Assuming that the HR20 and your Samsung have similar options, you should be able to have either the HR20 or the Samsung perform the video conversion. If one of them is having problems with the conversion, try changing your settings so that the other one is doing the conversion.
