Can't update Matrox DVD player

[claw]

Several posts have said that to update the Matrox DVD (Divicore model) player all you have to do is replace dvdpld32.dll in the Windows\System subdirectory with a newer version from a more recent Cinemaster release. When I do this, the player runs, but the opening screen is green cubist mishmash. Only the original version of this .dll seems to work.

I have a G400, and the version of the software DVD player that came with the card is 1.0.29.5356.

Any ideas? Thanks.
