I tried to copy a DVD burned with Edition using Roxio Disk Copier and it gave a warning error that the source disk was multi-session.

So, does anyone know if DVD's burned with the integrated Liquid Edition software are "finalised".? I am wondering if this is the cause of my problem.

I am having some difficulty with DVD's not playing on a variety of DVD players. I do not think this is a +R or -R issue because the players instruction manuals say thay they will play either. The disk are also high quality. The DVD players fail to recognise the DVD and most give the error message "Disk not recognised" or "Incompatible format" and do not play.

Any help or information will be very much appreciated. I have had no response from the Pinnacle Support Forum as yet!
