is there any reason to think that the file made with -vcodec libxvid
{ that i think is Xvid 1.3.1 isn't that true ? }
would not be backward compatible to xvid 1.1.2 ?
meaning play ok in any player that can play xvid1.1.2

  i did some googling -- and i current think
-vcodec libxvid  = =  XviD 1.3.1 = = xvid ISO MPEG-4. ISO -------is that 
true?
and
those files should play in anything that plays xvid 1.1.2

any wisdom would be appreciated -
