The comments where in jest, but just in case....i'm sorry. ANYWAY. The uncompressed idea didn't work either!! Worth a try though, the problem must be a bit deeper than I thought. Like I said before, bryce, illusion, and premier seems to output working avi's, so it must be a poser thing. Oddly enough premier PLAYs the avis, but wont turn them back into another avi file. So what I am doing is this.... Outputting the film as BMP sequence in premier, then loading them back in ready for the conversion back to a working avi. This does work but adds to my work load somewhat. Kev, take no notice of me, i'm a sarcastic bastard but the humour is lost in these messages. I'll buy you a virtual drink one day.
