Well, if you really want to check whether xvmc is working, the amount of CPU for mplayer's video output should be very low.
Check your mplayer status line. Notice the first two percentages : the first is the amount of CPU for video decoding, the second is the amount of CPU for video output.
When I play a 1920x1080 stream, the status is something like :
A:74406.8 V:74406.8 A-V: 0.014 ct: -0.673 440/417 24% 5% 0.5% 0 0 47%
(24% video decode, 5% video output)
