I called last night for the upgrade to the genie but could not get the guy (Paul) to sell me an AM21. First off he didn't know what an AM21 was, or what it was used for. I told him it was so I would see my sub channels in the on screen guide. Is this right, am I asking for the wrong thing? He kept insisting it would not work with the HR20 700, I told him I would not have the HR20 that I would have a genie, he said he could not write it up that way and I could call after the install and he could drop ship me one. I asked if he would please put it on the order sheet and he said that he would. Well got the email confirmation this morning and he did not do it. I'm a little bit confused do I or do I not need the Am21 to see the sub channels ? Install will be Wednesday morning between 8&12. My wife's two favorites are both sub channels, am I going to be in deep sh*t or what? After 45 minutes on the phone I gave up and said do what you have to do. Coming to you from Baltimore Md.
