I'd recommend calling D*, saying they replaced the HR20 with a HR22 and since they don't carry all your local ATSC HD channels on satallite yet could they please send you a AM21 for free so you get those channels back, many report getting free AM21's.
I did that today, as you said. No problem at all. Very pleasant CSR, and I didn't even go up a tier or so. What I've found with D* over the years is if you're decent to them they reciprocate.
Thanks for the advice. I know I could have done the same as the AM21 with my DTVPal units, but they wouldn't couple with the HR22-100 and the guide, nor record to the DVR. I'm good to go now.
tell them to temporarily change the hr23-700 model number to another hddvr model number. once that is changed remove the dvr service from the account and then reactivate it. it tricks the system into thinking it is adding dvr service to example: a hr21-***. once they have removed and reactivated the dvr service on and it's working. tell them to change the model # back hr23-700. since the whole modifying/changing the model number is something we almost never have to do please be patient with them. i sent out a order today to get this glitch fixed so it will be fixed promptly. which means i probably wasted my time letting you all know this. i guess if it helps even one person it was worth it. i just joined the forum today so if anybody has any kind of questions feel free to ask if i don't know right off,i'll get it. remember if it is a account specific question you would have to call or email dtv. thanks for letting me join and i'm looking forward to helping and learning as well.
