Hello, I am new to home theater...I have now idea about RPTV, the only thing I know is it has big screen. can someone point me a link about RPTV, and buying guide for a RPTV, e.g. what are must have functions? what are optional or nice to have functions? I got some questions too: 1: I heard RPTV uses a lamp in the big box, so how long can this lamp last? i.e. watch 6 hours TV per day. 2: the light is projected on the screen, but through what? a TFT or CRT screen? which is better? 3: my major video source is regular cable TV, so I guess the signal is 4:3, sometimes I watch DVD which I can consider it is 16:9 format. But later on I may switch to HDTV (either Rogers or satellite), so do you guys think 4:3 is ok for me or 16:9 is better? 4: people here are talking about HDTV, how about DVD, DVD is not HD? HDTV's resolution is higher than DVD's resolution? What's DVD's resolution? 5: what are the functions that a HD RPTV must have? what are optional or nice to have functions for a HD RPTV? 6: if I go with direct view HDTV, TOSHIBA's 36' 16:9 is about $3000 (canadian dollar), what do you guys think? any larger screen availabe for a resonable price? does it worth the money? 7: if I go with HD RPTV, for same price I can get a 47' SAMSUNG HD RPTV...what the best brand of a RPTV? is samsung reliable? or other big names like SONY (they are $$$), PANNY, TOSHIBA, HITACHI? 8: if I watch regluar 4:3 TV program, which 16:9 RPTV has the best stretch model/algorithm? 9: what's burn-in..? I know people worrys about it. I have tons of questions, hope you guys can help me out!!! Thanks a lot!!!
