I just recently purchased a Sony KV34XBR800 (after reading many posts on this board, and other online reviews). I currently have the TV hooked up to a cheap RCA DTV (it was free) receiver which is hooked to my oval dish with dual LNB. Do I need to upgrade that dish to a triple LNB to get HDTV or should I be ok with what I have? I am probably going to purchase a new receiver early next year. I don't know which one I am getting yet though. I am thinking about the RCA DTC-200 with DVI. Anyway, any help will be greatly appreciated. Thanks.
