I ordered the 722 and it will be installed on Thursday. However, I am now questioning my decision on the 722. I have one HDTV and one SDTV that will be hooked up. I would like to record multiple shows (Discovery and NICK) at the same time while watching another channel (ABC or ESPN) on one TV and CBS or NFL on the other TV. I am being told that I cannot do this with the 722. Can I do this with the hopper? It will be an additional $11 for the hopper, but I am unsure which option to go with. Any thoughts?
