I tried to record from an mpeg1 video file. avi2swf still can't convert the 
result. :(

I guess this is the case (sigh)
I have tried to convert each frame to a ppm file using transcode as described 
in other emails. 
With the resulting ppms I have tried to create an avi file using the mjpegtools 
suite (ppmtoy4m
piped to yuv2lav)

The resulting avi plays fine using lavplay from mjpegtools , ffplay from ffmpeg 
and mplayer. But
no luck converting.

I have also tried to use transcode to convert the ppm files to an avi file with 
xvid encoding, and
with ffmpeg encoding using in turn mjpeg codec and mpeg4 codec. No luck with 
avi2swf.

O.t.o.h, as mentioned before, turning the ppm files to jpegs with the convert 
(ImageMagick) tool
and then using jpeg2swf works fine. Its just wierd. 

Here are the command lines for each of these attempts, and the conversion 
attempt with avi2swf.
