Hey guys- First off, I am a complete newbie so go easy on me. I am building my first HT system and have some questions on TV's. I pretty much made up my mind on a toshiba. Either the 57h83 or the 57hx83. My questions are what are the big differences between the two. I have done some research and found these differences: Adjustable Dfine on the HX compared to just Dfine on the H Separate Woofers and Tweeters on the HX Theatershield on the HX cinema series monitor on the HX and theaterwide on the H TheaterNet icon IR control system on the HX I really don't understand what these features mean, so anyone who can put them into laymans terms I would be forever grateful. Also is the HX worth the extra $? One more thing, I would have to drive over 100 miles (or buy it on-line) to get to a dealer that carries the HX. Thanks so much in advance.
