I just changed out my old SD DVR for a new HR22 HD DVR. We watch some SD stations and I notice that the SD stations using the old DVR were really clear and clean very watchable but with the new HR22 they are very pale and low resolution like a VCR tape. Like they used to be before they put up more sats. I also have Dish and they look much better there also. Why would the look worse on the HR22 than an old DVR40?
