Terje,This is interesting information and more people would have access to it, if it was posted to the Forum instead of the mailing list. Casual users can look at the forum without joining and then could read this and a lot of the other non-CinelerraGG code specific emails/questions. A lot of users do not join the mailing list and never get a chance to view this helpful information.
