When setting the D3d9to9Ex parameter to 1 in dxwrapper.ini, RoQ videos (shown as an intro when starting the game and as briefings between levels) in Call of Duty 2 show only a black screen with audio playing normally.

The EnableD3d9Wrapper setting (whether 0 or 1) does not affect the black screen issue; the video remains black regardless of this setting.

I will be glad to be wrong and know that there is some special parameter that can correct this behavior, but I have not been able to detect it. I also did a check in Call of Duty 4, which uses Bink Video codec, and there are no problems, so I assume the problem has something to do with an outdated RoQ library or something else.
