--- Comment #8 from Lei Zhang thestig@google.com 2008-05-09 12:07:57 --- Created an attachment (id=12843) --> (http://bugs.winehq.org/attachment.cgi?id=12843) patch to recognize 24 bit videos as non-8 bit videos.
So it's trying to parse a 24-bit video, except we don't know anything about that format. You might want to ask Mike Melanson from http://multimedia.cx/ about it.
The attached patch will let you continue, but I have no idea if it's correct.
