I installed Windows XP as a guest OS on Fedora 12 x86_64. I have a Geforce 8600GT graphic card on the host. And then I installed nvidia-195.36.03 drivers for Linux. VDPAU is working. What should I do to make 2D video acceleration work?

I have enabled 2D video acceleration option on the VirtualBox panel. But it seems not work. What should I configure on the guest OS? Just installed PowerDVD and enable DXVA in the panel?

You need to install the guest additions (in the guest) and while the Windows guest is in safe mode.
See sections:
4.9. Hardware 3D acceleration (OpenGL and Direct3D 8/9)
4.10. Hardware 2D video acceleration for Windows guests
In the VirtualBox Users Manual.

You can not install 3rd party video drivers in the guest. It must use the VirtualBox video driver.
