Windows Meida Player 9 only plays DVD sound

My windows media player 9 only plays DVD sound :(
I have WinDVD platinum (latest version) and also latest driver for my TNT 32 card installed.
I tried DVD decoder pack for Windows XP with no luck. The only work around i found for that was installing nVidia NVDVD 2.2.7 . But it (NVDVD) really sucks and does not play good, and i dont like it.
Any idea?

Why not just use WinDVD? :confused:

Wmplayer is pants, generally. Bloated too.

Its not the matter of what to use. Its the matter of the technical problem i am facing.
