Ok, just got my Mit's 55313 HDTV and tomorrow DirecTV will be out to set up my satellite. I bought the Hughes E 86 HD receiver for the Mits not knowing that the TV had a DVI connection. (no one could tell me what was on the TV, its not even listed in the main sight for Mitubishi. Once I got the tv in today I was surprised to find out that in fact it did have that type of connection. A few of the questions that I have are relating to weather I should return the Hughes and get the Samsung as it does have a dvi connection. After reading more about the two receivers I am finding out that the Samsung can receive bot HD and SD at the same time. Is this ma major thing? What makes this better then the Hughes? Would I have to switch something everytime I go to a HD channel with the Hughes receiver? Next question is how do I receive a HD signal of over the air channels. People are telling me that I can not get CBS, ABC, NBC, or Fox in HD because DirecTV does not send those channels in HD. They tell me that I can receive OTA signals with my Hughes receiver, but what do I need to add so that I can get these channels to work? That is all that I can think of right now to ask, but rest assured that in a few hours I will come up with even more questions to pester you all with. I am reading as many threads as I can tyying to learn about HDTV, but most do not seem to relate to the issues that I have. Argh! Thanks in advance for any help that you may provide me.
