connection help

[llzel]

I want to lease a 3rd IRD, a 211 for my bedroom. Would this connection work:
TV2 output from a 722 to a diplexer along with the sat cable to the 211. At the 211 use another diplexer to separate the TV2 output to the TV antenna in and the sat to the new 211.
With this set up I can watch a DVR program (SD) if I want or HD with 211 through video input.
would this setup work?

The 722 rf output is in either analog or cable while the tuner in the 211 is digital. You can hook the 722's rf output directly to the tv but not thru the 211 nor would the rf output give you HD on the 722 line.
