I am reevaluating the codecs I export to just because it's to hard to find 
an MPEG-1 in linux.

I couldn't see it. WMP even tried getting a codec from internet.

I couldn't see the animation. MPG-1 ensures universal viewability and is the 
standard courtesy for this forum (or so I've heard).

It's funny.  I've often found that even the best MPG encoders (TMPGENc) 
would often choke on an extremely short and boring (little action, lotsa 
black) animations-- something must have just gone wrong with the processing 
in the MPG encoding algorithm. I would (IIRC) get no anim at all-- no .MPG 
file.

No here,  with an extremely boring anim (little action, lotsa black)  ffmpeg 
did not choke, it in fact created an anim that Kaffeine in linux could see 
but Windoze *could not*.  WTH?

I add some complexity and white background to the scene , a voila! I get 
this anim with the exact same keystrokes.  it plays on linux's kaffeine and 
on WMP on my winxp box.  WTH?

That's wierd. I've never had any problems with TMPGEnc, even on pretty 
short anims (though I tend to never do anything shorter than about 25 
frames). Have you tried using different compression modes? I always use 
"Constant Quality" at 25fps and everything else is just default options.

Tek, I know you to be one very talented guy.  Ever tested the limits of
boringness?  Someday I'll post the code that caused this problem, maybe
after I've had a chance to test it with TMPGENc.
