I didn't know there were different formats of this disc. I bought it to make sure I'm getting the best possible picture from my 57" JVC HDTV(rear projection). When I read the back of the case it noted that there were three versions of this disc. NTSC, PAL and a HDTV version. Do different TV's have a different reception format? I just got the PAL version of DVE but my TV's reception format is NTSC. Is there a difference between these 2 formats? Any thoughts are comments would be much appreciated. Thank you in advance.
