divx 5.0.3 Pro is free of charge for people who use it just to decode films.
You have to pay it if you encode films ( using anysoft: easydivx, divxmachine,neodivx...) and if one installed ( or got installed ) divx 5.0.2 one can get divx 5.0.3!!!
I know that problem to a much bigger scale because I run XP and my friends 2000!! and F***!!! 2000 is real C***!!!!! It can hardly read the cds I burn ( and all XP computers can!! ).
I thonk that the codec choice is left ONLY to the guy who rips and encodes the films, the simple users just follow the rippers choice. if ripper wants 5.0.3 then it's 5.0.3 and he wants 5.0.2 it's 5.0.2 ( But it won't be both )
You just have to know were you are ( user or ripper ).
( Sorry if I'm being rude to someone, it's not the point!!
