It'll play on my mom's compy, but not mine.

I’m a little confused with this.
I have the latest version of SMplayer and I’m trying to watch some .mkv files on it.
The video is “1280×720 16:9 H264 (~1700 kBit/s)”
And the audio is “Japanese 2.0 AAC (48.0 KHz)”
When I try to play them, they’ll play the audio for a split second, and then stop.
But if I try to watch them on my mom’s computer, (again, with SMplayer, and both computers use Windows XP) they play just fine.
So I think I’m missing some kind of plugin/patch/something.
Does anyone know what I need?
I’ve been googling but I haven’t found a fix yet...

EDIT: Oh yeah, I did try installing the CCCP a couple days ago, and it didn't make any difference, so I uninstalled it last night.

Copy here the mplayer log (options -> view logs) after you tried to play that file.

It seems the directx output doesn't work. Go to preferences -> general -> video and select another one (direct3d should work).
