I've looked around in the faq's and forums and they all have that
problem. They only hints are:
- compile ffmpeg with -O5 (per default it is -O2); this does not
  helped much;
- lower the screen size
- lower the bits per pixel to 8
- lower the frames per second
someone claimed that it should work fine with 1024x768, 8bpp, 10fps;
when I have more time I will try 8bpp too;

I use 'mutt' and a r)eply would send the answer to you only, while
a g)roup-reply send a Cc: to the list;
