Could it be that aviplay is not relying on the colour depth reported by the 
avifile 'library' (not
sure if thats the correct term here) but is finding the colour depth using its 
own function ? I
haven't looked at the code, I'm just making a wild guess.

I am also certain the webcam does colour because I have gnomemeeting installed, 
and when I turn it
on the video window is in colour. The same thing happens with the program 
camstream.

Sure, I can do that. Tell me how you would like it sent, and I'll try sending 
it.

Thanks for the info. Now, if nothing else works at least I have one sure way to 
convert avi files
to swf, even if it it slightly roundabout :)
