I'm a newbie to setting up a home theater. I'm planning to buy a RPTV (around 50"). Btw, I'm located in Canada. I noticed all the shops are selling widescreen TV and HDTV now. The question is I'm not sure I should get a WS TV. I noticed the viewing screen will be smaller on a widescreen or stretched. Also, the salesman said in the future (in 5 yrs or so), many programming will be switch to HDTV format. Is that true? Would it be silly to get 4:3 HDTV now??? I'm very confused... Any comments/help are appreciated!!!
