Re: Projection vs LCD
dvd's are 720x480 and they're anamorphic (most of them) which means they look much better than standard SD.
Anyway, go with rear projection. I've got a JVC LCoS 52" RPTV and it freaking owns. Either get like that Sony 60A2000 or you may want to consider the JVC 61FN97, it's like $2500 nowadays and it's pretty kick ass.
