Ok, this is a weird one...

Lately I've been finding some videos are not playable using mplayer on my media 
center frontend. Which is kind of, you know. It's job. These videos pretty much 
hang with the message:

    Unexpected decoder output format Planar YV12

repeated constantly.

Now the funny thing is they play just fine on another machine, with hthe same 
version of Ubuntu, same version of mplayer, same version of the nvidia binary 
driver, same vdpau, etc.

The only difference I can find is this. When I run "vdpauinfo" on the media 
center, I get (among other results) this:

   Decoder capabilities:

   name               level macbs width height
   -------------------------------------------
   MPEG1                 0  8192  2048  2048
   MPEG2_SIMPLE          3  8192  2048  2048
   MPEG2_MAIN            3  8192  2048  2048
   H264_MAIN            41  8190  2032  2048
   H264_HIGH            41  8190  2032  2048
   VC1_SIMPLE            1  8190  2048  2048
   VC1_MAIN              2  8190  2048  2048
   VC1_ADVANCED          4  8190  2048  2048


On the machine that IS capable of playing the videos, I get all those and in 
addition get these:

   MPEG4_PART2_SP        3  8192  2048  2048
   MPEG4_PART2_ASP       5  8192  2048  2048
   DIVX4_QMOBILE         0  8192  2048  2048
   DIVX4_MOBILE          0  8192  2048  2048
   DIVX4_HOME_THEATER    0  8192  2048  2048
   DIVX4_HD_1080P        0  8192  2048  2048
   DIVX5_QMOBILE         0  8192  2048  2048
   DIVX5_MOBILE          0  8192  2048  2048
   DIVX5_HOME_THEATER    0  8192  2048  2048
   DIVX5_HD_1080P        0  8192  2048  2048



This is the only difference I can find. And I have NO IDEA where it's coming 
from, or if it has anything to do with anything, or if ANY of this makes any 
kind of sense.

Anyone have any ideas?...
