The Dolby Digital and the intro movies will play when I start the game up. However, all of the other movies do not play during the single player game. Does anyone know how to fix this?
Thanks.

Nobody has any ideas on this?

If this is referring to Descent 3, I have the same problem.

Using Windows 7 Home Premium 64-bit, nVidia 8800GT, Intel Core 2 Extreme QX9650.

I've been running Descent 3 in OpenGL mode.. when I get back on that computer I might see if Direct3D mode allows the movies to work correctly.
