OK, I put the driver in the RT21 dir.

Do you know any player that can play Indeo 2 on Windows?  Which Indeo
codec package did you stumble across?  I found the following:

http://dvd.box.sk/index.php?pid=soft&prj=info&pol=2&rid=4012

It contains IR21.DLL, dunno if it is the same one, I'm on the run now
and will investigate later.

BTW, if you upload something to MPlayer FTP, please also add a .txt file
with the same name so we know what it is.  Otherwise chances are it will
be deleted without investigation.

Hmm, I'm still sceptical since the first version of your decoder did not
produce the blocks IIRC.  Unfortunately I do not have it around to
compare right now.  Could you please resend it to me (in private) so I
can compare?
