Any significant differences between these 2 units? I don't need or want a 522, at least for now. This will be my 1st DVR from Dish, with several yrs. with just the basic receivers working well. Any pitfalls I need to be on the lookout for? Dish has this deal where you can give them 25 bucks plus your old receiver in exchange for a new DVR. Good deal, or has someone done this and not gotten what they expected? I have a 4900 and a 300 series receiver now (about 3 -4 yrs old each) Finally, will I notice less compression artifacts with the newer receivers? I have a 2 yr old Sony connected via S inputs. Good, strong signal on both sats, so I'm wondering if the artidacting is due to the signal coming fron the broadcasters (only certain channels) or is it just time to upgrade my receivers??
Thanks,
