My HR44 was just installed today and it looks and functions great on my 55" LCD.
I put a C41 client in my theater with 106" projection screen and it seems to me that the PQ is a bit lower from the HR21 that it replaced. Especially in the guide. I made sure the client was in 1080i resolution but the guide font still looks a bit fuzzy.
Does the smaller client imply less horsepower and perhaps some cut corners in some of the processing? If that's the case I'll probably swap the genie into the theater or replace the client with an HR24.
