Same MD5, still I get:

get_path('subfont.ttf') -> '/home/root/.mplayer/subfont.ttf' 
Unicode font: 255 glyphs. 
Floating point exception
2006Apr25/main# 

Same with mencoder versions from Feb2005 to Apr2006.  And whether
compiled with gcc 2.95.3 or 3.3.6 (in debug mode no less).  If anyone
else can get this working (on Linux), I'd certainly want to know how.  

Of course, it looks like you're using mencoder under Windows, which
would explain it.  I suspect MPlayer doesn't use the wine DLL
loader code when it's actually running under Windows :-)  In fact I
expect that a *lot* more codecs will work under Windows than on other
OSes.

Looks like you left out the MD5 for:
aslcodec_vfw.dll: 608af234a6ea4d90cdc7246af5f3f29a
ViVD2.dll: a7b4bf5cac630bb9262c3f80d8a773a1

MD5 mismatch for:
m3jp2k32.dll: f3c174edcbaef7cb947d6357cdfde7ff
m3jpeg32.dll: 1cd13fff5960aa2aae43790242c323b1

My codecs are from "all-20050412.tar.bz2" and
"windows-all-20050412.zip".

A handful, but it's probably better to stick to codecs which are in the
codecs packs right now.

Arg!  It wasn't a very thorough test, there are lots more failures:
 
asusasv2.dll asusasvd.dll wnvplay1.dll and wnvwinx.dll are
just failing quietly, and not outputting any video.  

avimszh.dll is only outputting colorful static.

mcmjpg32.dll wnvplay1.dll and wnvwinx.dll are not outputting anything
playable (bluescreen--perhaps a colorspace problem?).

jp2avi.dll apparently needs "-vf flip".

Very sorry :-(


Here's a far better script, which just writes the files, and requires a
human to check them: 
____
for CODEC in /usr/local/lib/win32/*.dll
  do CODEC_BASE=`basename $CODEC` 
  mencoder -nosound -ovc vfw -xvfwopts codec=$CODEC_BASE \
    VIDEO.avi -endpos 30 -o TEST-"$CODEC_BASE".avi 
  rm "`du -k TEST*.avi | awk '/^0/ {print $2}'`"
done
____


And if anyone cares, vp7vfw.dll: cb4cc3d4ea7c94a35f1d81c3d750bc8d 
mostly works but writes the wrong fourcc, and "-ffourcc VP70" doesn't
work.  Manually putting the correct fcc into the header (byte 00000070
and 000000BC) allows it to playback with Windows players (MPlayer
doesn't support VP7 playback yet).
