Thanks for your answer.  I have never had to use a fifo before so I 
didn't release you can do that.

Now, how about being able to simply extract the audio and video stream 
from an AVI file and put it into a Quicktime file without any 
conversions.  How about the reverse.  Also how about taking an AVI file 
with Mpeg video in it (courtesy of MEncoder) and creating a valid Mpeg 1 
system stream.  Or what about being able to fix broken Quicktime or AVI 
files, such as Quicktime files that don't have any codec code in it?

Thanks in advance.
