I went into Rex's today and was looking around and saw the Sony KV-36HS20 and the picture quality was astounding, but being new to the hobby (I'm not that knowledgable about HDTV), I have a few questions. What is the difference between HDTV, RPTV, and FD, (pros and cons) and which one does this unit fall under? If it is HDTV, do you have to have a HDTV tuner in order to use the unit??? Also will video games 'burn' images into the unit after prolonged usage? And has anyone had or have heard of any problems with this unit (short term or long term), I mean for $2300 dollars, I would like to get all the input I can before spending that kind of money. Again, sorry for all the questions.
