Problem running games with video files [SOLVED]

[zabnat]

I seem to have problem running some games and managed to trace the problem to the video (wmv) files they use.
If I remove the video files, game gives me a message that they are missing, but otherwise runs normally.
When video files are present, the game freezes when it begins to play the video and does not respond to close window commands any more. I have to kill the process from task manager. When it starts to play the video it gives one tick of sound and then freezes.
Video files play normally on all of my media players.
For example the problem occurs with Dualnames' LoneCase (AGS 2.72.920) and ONNA (AGS 3.01.1018). With ONNA the problem can be worked around by choosing Direct3D 9 as display driver. But even then, the video does not play, only sound is heard and the game window is transparent.

Is the problem in my computer (Windows XP) or on my video codecs or in AGS? Probably my computer as nobody else seem to have these issues? Does anybody know how I can fix this?

It's probably something to do with your video codecs because the Direct3D driver uses a totally different API for playing the videos. Therefore if it doesn't work with either that would seem to indicate some sort of codec problem -- but it's strange if they play normally in Media Player and other applications...

It's funny that when you post about your problem you usually immediately solve it yourself
The problem was in ffdshow, which had the settings to be used on all wmv decoding. I changed the setting and now the games seem to work and play the videos ok.
