The screen was all white for entire duration of the clip the output from
mplayer was this:

BENCHMARKs: VC:  15.002s VO:   3.406s A:   0.000s Sys:   0.190s =   18.599s
BENCHMARK%: VC: 80.6615% VO: 18.3154% A:  0.0000% Sys:  1.0230% = 100.0000%
*** glibc detected *** mplayer: double free or corruption (out): 0x34aa6008 ***
...

MPlayer interrupted by signal 6 in module: uninit_vo
- MPlayer crashed. This shouldn't happen.
   It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
   gcc version. If you think it's MPlayer's fault, please read
   DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
   won't help unless you provide this information when reporting a possible bug.


It also printed:

[swscaler @ 0x106a5b50]ALTIVEC: Color Space BGR24
[swscaler @ 0x106a5b50]using unscaled yuv420p -> bgr24 special converter
