When DVD's are listed as widescreen 2.35:1 and also as 16x9, does this mean that two formats are on the same disk? I notice that some are listed as 2.35:1, 16x9 yes and some are listed as 2.35:1, 16x9 No;can someone explain this to me? I am getting a Sony36XBR(16x9). How will differing widescreens show up on it? How will 4:3 show up? I presume I'll know in due course -=- TV and DVD are being shipped and at present I don't have any DVD's.
