ff*vdpau do not "listen" to threads, skiploopfilter and fast, only skipframe has
an effect.

Note that feature set A is fast enough for any BR material, and all Nvidia
hardware (at least including GT220) cannot play 1080p50, so for H264, the
feature set should not make any difference for real world samples (except that
feature set B fails completely for some).

If you are using a 24Hz TV and a 1080p24 sample, MPlayer svn will probably not
work correctly, everything else (fps > Hz, I just tested 50fps on 60Hz for
several hours) is expected to work, bug reports are welcome.
Don't forget to also run qvdpautest, if it shows absurdly low values for H264
(<30fps), you should post a bugreport on nvnews.net.

Please post complete, uncut output of latest svn, Carl Eugen
