Wait, do you mean that ffmpeg DOES support wmv (wmv8
and older)?  It supports WMV without the DLL codecs? 
This is what I get when I run it:

ffmpeg -i my-file.wmv /tmp/hello.mpg
FFmpeg version HEAD, Copyright (c) 2000-2004 Fabrice
Bellard
  configuration:
  libavutil version: 49.0.0
  libavcodec version: 51.9.0
  libavformat version: 50.4.0
  built on Jun 17 2006 16:26:53, gcc: 4.0.2 20050901
(prerelease) (SUSE Linux)

Seems that stream 1 comes from film source: 1000.00
(1000/1) -> 30.00 (30/1)
Input #0, asf, from 'my-file.wmv':
  Duration: 00:02:49.2, start: 3.000000, bitrate: 136
kb/s
  Stream #0.0: Audio: wmav2, 22050 Hz, stereo, 32 kb/s
  Stream #0.1: Video: WMV3 / 0x33564D57, 320x240,
30.00 fps(r)
Output #0, mpeg, to '/tmp/hello.mpg':
  Stream #0.0: Video: mpeg1video, yuv420p, 320x240,
q=2-31, 200 kb/s, 30.00 fps(c)
  Stream #0.1: Audio: mp2, 22050 Hz, stereo, 64 kb/s
Stream mapping:
  Stream #0.1 -> #0.0
  Stream #0.0 -> #0.1
Unsupported codec (id=74) for input stream #0.1

This is with the latest ffmpeg sources from SVN today.
 Am I doing something wrong, or is WMV not supported,
or?

Right, I realized that MPlayer did some amazing little
tricks (including bits of wine) to do what it does. 
So if I simply want to grab frames out of videos like
the one I tried, do I need to start hacking on MPlayer
code, or?

I'm basically looking for direction on this.  I see
reports of ffmpeg being able to handle WMV but I'm
obviously not getting something.

Thanks for your help.
