Hey guys. Hoping some of you Satty gurus here can help a brotha out. I currently have Dishnetwork with the DISH 811 HD receiver. I would love to get in on some DVR/PVR action but I simply cannot afford the 921. Is it feasible for me to pickup a nice 508 or compatibile PVR unit and run to a seperate input on my TV, giving me the option of recording shows as well as watching the occassional HD goodness on the 811? Is anyone else doing this or considering it? Your thoughts would be appreciated.
