I dont know if they can bill you for HD as the account probably shows no HD dish. I know with my setup I had to wait. I have 2 R22's which can be used on a SD only account or be set up for HD as long as a "real" HD receiver is on the account. So I have a H23 in the bedroom on a SDTV and the 2 R22's are on the HD units nowCall them to activate card and still receive SD TV thu the HR24 till Thurs when HD Dish will be installed. They will probably start billing me for HD service on the day I call, no big deal.
Is this accurate in that I can use the HDDVR to receive my SD DTV channels thru my SD Dish till the 30th?
yep. I do that with one of my receivers
