Yes this problem is most likely related to the frame rates. It's a
limitation of the VDPAU driver (also shared by some other video outputs)
in MPlayer svn.

Try compiling a player from
git://repo.or.cz/mplayer-build.git

That has superior VDPAU support and should avoid this problem.
(Depending on your linux distro there may be precompiled packages
available in case you don't want to compile yourself.)
