I am wondering how many tuners I can have on my account. If I go out and personally purchase 3 722s and put them all in Single TV mode, will that fly? When I got the 722 I have today it seemed to cause a problem that I wanted it to run in Single mode because I already have 3 other receivers with one tuner each, meaning I have 5 total tuners on my account. Does it make a difference if they are leased versus personally owned? Just trying to find out because I would like to run at least three dual tuner DVRs in single mode if possible. Thanks for any help.
