I still get an error:

===========================

That takes ages to finish, and the resulting file, while a plausible size
(19M), is "data" according to "file", and neither RealPlayer nor mplayer
will play it. Am I screwed, because of mplayer not understanding the codec
used (RealPlayer 7 does, BTW)?
