playing multimedia content under openbsd with Xvid and mplayer

hello.
I just installed OpenBSD3.5 and now am using gnome2.4.
i've installed mplayer from the openbsd.org packages directory and it seems to work with all kinds of media.
The trouble is, it plays all videos too fast. The picture rate is too high and sound is too fast, too.

I wonder if anyone knows how to solve this problem.

thanks in advance

ive had that problem on windows way back when i used to use it. its just one setting you change. go to the mplayer home page and look for a troubleshooting guide.
