--- Comment #11 from Dan Kegel dank@kegel.com 2008-09-15 13:21:27 --- Hmm, http://blogs.msdn.com/matt_pietrek/archive/2005/02/04/367494.aspx mentions the MSDIA sdk as a way of accessing these files. Perhaps fuzzing that would be enlightening.
MSDIA is documented here: http://msdn.microsoft.com/en-us/library/x93ctkx8.aspx and mentioned here https://www.gwydiondylan.org/cgi-bin/bugzilla/show_bug.cgi?id=7078#c11 Looks like MSDIA dlls are included in the visual c++ 2005 runtime redistributable.
