I am looking to purchase a Dish Network HD receiver on e-bay. I am wondering if I can use the Dish 811 receiver or the newer vip 211 with a Dish 500 and a Dish Pro LNB. I am not looking to sign up with HD programming right now. I just want to take advantage of the up-conversion feature that both offer. With the 811 it connects to the HDTV with DVI-HDTV/DISH DVI (DVI-D) and HD Component video outputs. I only have HDMI inputs. If I use a DVI to HDMI cable will I loose picture quality or should I get the vip 211 with the HDMI output? Any help would be appreciated.
