I currently have a Dish 512 receiver that is located outside my room so I have a UHF remote to control it. I purchased a new TV and it does not have the Svideo connection only HDMI and the AV input, when I connect to the AV input it looks terrible, everyone is telling me that I need to connect with HDMI, but there is no HDMI on the 512, called DISH and they want to send a tech out and replace everything and make me sign up for a 2year contract and some other fees. Can't I just get a 612 receiver and connect it to my existing dish and cables? I only care about the basic channels, not looking for HD just looking for a decent picture. Thanks
