It probably has a lot to do with the scalers in both MediaRoom and the TV. Also, I don't know if the channels being pushed are switched between 1080i or 720p but you are forced to choose one or the other on FibreOp so for my projector which is native 720p, I set the FibreOp box to output 720p. For the LCD in my bedroom which is native 1366 x 768 I tried both FibreOp box set to 720p and 1080i and I found 1080i to look better. The problem is there could be a ton of scaling going on. Examples:
1) CBSHD sends 1080i - FibreOp box pushes out 720p - TV scales to 1366X768 - scaled twice
2) FOXHD sends 720p - FibreOp box pushes out 1080i - TV scales to 1280X720 - scaled twice
So the ideal situation would be either of the two:
1) FOXHD sends 720p - FibreOp box pushes out 720p - TV scales to 1280X720
2) CBSHD sends 1080i - FibreOp box pushes out 1080i - TV scales to 1920X1080
So the quality of this HD in my opinion is poor overall but given the factors above either the FibreOp box scaler or TV scaler being poor could make things even worse.
I believe on other providers each station or network will send the signal out in either 1080i or 720p but I have no idea what happens with FibreOp if everything is converted to one or the other and then sent down the pipe or the FibreOp box scales the stations depending on how you've set it to push it out.
