Re: 1.0-9746, 1080i output and interlaced video
I just reinstalled slak to 11 - current. I notice xvmc works fine with nothing but xorg.conf in /etc/X11. That makes sense as it's the Nvidia installer that adds the xvmc libs.
You need to build mplayer with xvmc although I believe xine will work.
Mplayer needs --enable-xvmc --with-xvmclib=XvMCNVIDIA to build support for xvmc.
