After creating a file with Fairuse, if you run a completed file(movie) through AVIcodec or GSpot, the File info shows the Fair-Use website address and an advertising line saying this is the best and really easy software. Can this be changed? Can I add a line so that I encode a movie with my name also? Thanks for any help.
