It is only the webcam stream that gives you this error right?

This is the known problem on snap 5 and snap 6. It is not all that see it 
and it seems to be very dependent on timing.

I have some ideas of how to fix it if it turns out to be timing. I still 
wonder why it happens though.

The previous versions of Motion send the webcam stream as writes of max 
2048 bytes at a time.
The WebcamCompressInMemory patch  ( 
http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory ) 
introduced writing the whole shebang in one go and this seems to fail. I 
don`t know why. It fails in Palantir, Cambozola and Firefox. So it cannot 
just be a client problem. The minute there is some delay between like using 
my mjprox project or viewing the stream through an ADSL it goes much better 
though there are still some strange errors seen.

It has been difficult to get people to fix it because I was the only one 
seeing the problem but now we are at least two.
