In the Charlie Chat, and now mind you I have a toddler so I missed most of the audio, they said you can upgrade to an HD DVR for $25.00. Was that for a single or dual tuner HD DVR? I just got off a chat with a customer service rep. who said I could get a single tuner for free or a dual tuner for $50.00??? Where did the $25.00 come in there? I know I havent been a dish customer forever, but I have been here for nearly 3 years now. Thanks!
