yes. The R22 to have HD on it requires a "legit" HD receiver on the account (HR or H). Believe me..been there tired that (HD with just the R22)Will the R22's lose HD programing if you get rid of the HD receiver?
What concerns me more though about your 2DVR's and HD receivers is all the satellite dishes you have.
Do you see lots of helicopters fly over head and see black SUV's driving by your house?
nope only have 4 dishes that are visible
