hi Crusty - thanks for the link. I'm importing avi files into Workshop so it is encoding them to mpeg2 for the first time. I'm starting to wonder if it is someting to do with the camera because it only happens with one particular one. Mind you, the avi files look absolutely fine before they are burned to DVD.

Any more advise would be great because it's really starting to bother me as I've got lots of work to complete.

cheers
