Exporting a BLOB from ACCESS using VB

Hi,

I have this problem that I cant solve. I need to be able to have a button in a access form that exports a BLOB field to the file system. this BLOB is using only to store movie files when content people record the movie and store them there. Using Microsoft's site code, I was able to, but the file is coming out corrupt. The way used by the content people to store the movies to the DB is by inserting the file into this "bound object" in access. How cam I make this work?

Thanks.
