Thanks for your reply.
Sadly, I've not (yet?) been successful with this.

I'm crossposting to ffmpeg-user at lists.sourceforge.net (cf. 
http://lists.sourceforge.net/lists/listinfo/ffmpeg-user), because 
reading that mencoder can't do the desired conversion, this issue 
really pertains to ffmpeg then.

The ffmpeg version I'm using is:

ffmpeg version 0.4.9-pre1, build 4750, Copyright (c) 2000-2004 Fabrice 
Bellard
   configuration:
   built on Mar 27 2005 18:44:34, gcc: 3.3 20030304 (Apple Computer, 
Inc. build 1495)

I've tried:

	ffmpeg -i intro_1.wmv -acodec copy -vcodec copy -f mov intro_1.mov

and what I get is:

ffmpeg version 0.4.9-pre1, build 4750, Copyright (c) 2000-2004 Fabrice 
Bellard
   configuration:
   built on Mar 27 2005 18:44:34, gcc: 3.3 20030304 (Apple Computer, 
Inc. build 1495)
Input #0, asf, from 'intro_1.wmv':
   Duration: 00:35:00.7, start: 4.923000, bitrate: 25 kb/s
   Stream #0.0: Audio: 0x000a, 11025 Hz, mono, 10 kb/s
   Stream #0.1: Video: MSS2, 640x480, 1000.00 fps
Output #0, mov, to 'intro_1.mov':
   Stream #0.0: Video: MSS2, 640x480, 1000.00 fps, q=2-31
   Stream #0.1: Audio: 0x000a, 11025 Hz, mono, 10 kb/s
Stream mapping:
   Stream #0.1 -> #0.0
   Stream #0.0 -> #0.1
Could not write header for output file #0 (incorrect codec parameters ?)

however:

$ ffmpeg -i intro_1.wmv -acodec copy -vcodec copy -f avi intro_1.avi

"works", but sadly it does not produce a file QuickTime can read with 
the EnSharpen codec.

I then did some more searching and found that *supposedly* the 
Techsmith Screen Capture Codec (TSCC) is supported by ffmpeg (at least 
in principle) either through a file tscc.c or though a Windows DLL 
tsccvid.dll.
Now I don't know if the tscc.c and Windows DLL solutions really depend 
on each other and are part of the same thing. I am fairly certain 
however, that I can't use the DLL because this is on an iBook running 
Mac OS X 10.3.8.

Does anyone has any further ideas on this?
Again, I want to either do a container-level conversion from wmv file 
format to mov file format or find a way to view/convert the wmv file 
format EnSharpen encoded video in some other way.

Many thanks,

Thanks and regards,
Jens Ropers
