Hello. I'm scheduled to have an HD DVR installed on Friday morning. I currently have a H20 Receiver with HD Access. I assume the best bet would be to upgrade my programming package the Xtra HD DVR package since everything I need is included. My question is do you think I should just go ahead and change the package online today so that it's done and ready for Friday or should I just wait and let the installer call and make the change Friday morning. I've heard that sometimes the installers will do it for you and other times you have to do all of the activation. What do you think? Thanks
