I have one DVR 510 and one regular receiver, I wanted to cancel the extra receiver fee and the DVR fee. I was out when I called Dish Network to cancel. She said I will be able to watch recorded programs still on the DVR, but she wanted to know the serial number of the DVR. Since I was out I couldn't provide it then. But I was wondering, does that mean she will lock the DVR, so that it doesn't receive any channels nor the watching recorded stuff on the DVR. Which receiver does she actually deactivate so that I don't get charged for the extra receiver. Ofcourse I guess I will not be able to record since I'm going to be cancelling the DVR fee, but will it just receive channels if she cancels the other receiver. Waiting for answers so that I can call them & cancel this extra charge.
