I've spent some time to night doing a trivial benchmark of mplayer
on Red Hat 9 and OpenBSD 3.4-current (from CVS a few weeks ago). 
Each OS was intalled without any tweaking or patching which amongst other things
leaves us with gnome on Red Hat and fvwm om OpenBSD.  The Red Hat was installed
as a "developers workstation" (or whatever it's called, workstation + developer
tools). On OpenBSD I had to install gettext, iconv and gmake (the former are
required by the latter).

The computer is a ASUS P2B-S with a PIII/500, 640M RAM, Matrox G400 MAX
(I can get a dmesg to morrow). 

Here's what mplayer has to say about file.m2v:

Playing file.m2v.
MPEG-PS file format detected.
VIDEO:  MPEG2  480x480  (aspect 2)  29.970 fps  2520.0 kbps (315.0 kbyte/s)
========================================================================== 
Opening video decoder: [mpegpes] MPEG 1/2 Video passthrough
VDec: vo config request - 480 x 480 (preferred csp: Mpeg PES)
VDec: using Mpeg PES as output csp (no 0)
Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.
VO: [null] 480x480 => 640x480 Mpeg PES
Selected video codec: [mpegpes] vfm:mpegpes (Mpeg PES output (.mpg or Dxr3/DVB c
ard))
==========================================================================

First try was mplayer -nosound -benchmark file.m2v -vo null:

I am quite surprised...
