I am a current DishNetwork customer, and I have 6months left on my "contract" - I have the DVR522. I just purchased a Samsung plasma television - and started my switch to the HD world. The plasma is the second tv. I wanted to see if DishNetwork had any sort of "upgrade" options for current customers, but they said they do not offer any upgrades to HD at the moment. So I bought a Samsung OTA tuner to receive my local channels in HD - but I am still trying to pursue getting all the HD channels offered by DishNetwork. Does anyone know of a good way of doing this? So far, my only thoughts are buying a DishNetwork HD receiver from a retailer. But I don't know if I can hook that up into my current set up or not. Please advise and/or help.
