Derek/VDR User uses xine as his vdr plugin and he uses vdpau, perhaps
you should not use a software de-interlacer/post plugin, but rather
tell vdpau to enable de-interlacing. on xineliboutput I use the tvtime
output plugin, where I tell it to use my video output driver's
de-interlacer.

8200 should be supported http://en.wikipedia.org/wiki/Nvidia_PureVideo

Hope this help, search the forum for Derek/VDR xine's command line.
