I did not look at your attachment (and the error message 
you see) but the xvmc decoder cannot be used from ffmpeg 
(the application), it is used with the following MPlayer 
command line:
$ mplayer -vo xvmc -vc ffmpeg12mc
(and nowadays mplayer -vo xvmc -vc ffmpeg12)

I suspect it does not only work with MPlayer but that 
was the application it was originally written for.

Since it does not work with new (and middle-aged) 
Nvidia hardware and does only support MPEG1/2, it is 
often not (anymore) a recommended way of decoding.
