Because doing a google search for 'sony support BDP-BX2' (without quotes),
then typing divx in the top right corner search box on the offcial sony product support page (
http://esupport.sony.com/US/perl/mod....pl?mdl=BDPBX2 )?
AFAIK (after little research), no Sony Bluray players currently support divx (with the exception PS3).
Some that definitely support it (> year old news) are some players from Panasonic, Philips and Denon. One LG player is DivX HD certified.
