You updated to the latest MPlayer SVN and/or replaced your codecs.conf? (I forgot to bump the codecs.conf version so it might not print the warning it should if you have your own). 
If it still recognizes the ffmpeg12vdpau something is still on the wrong version.

Optimization and hardware acceleration are somewhat different cases. 
Hardware acceleration implies overheads like I/O, interrupts, memory transfers etc etc which improve relatively slowly, slower than CPUs (even if most of the CPU improvement is now based on more cores).
The result is that for most hardware acceleration comes a point where using it makes things slower. That point as far as I can tell has come and passed for MPEG-2.
As it's fast enough either way it hardly matters, but it might be wasted time getting it to work for most.
