Thank you for your reply. I just copied the footage into my computer. When I selected the footage to put into Studio it was as a avi file. I never changed it from the original footage. The main footage was from the Sony DCR SR42E. The final output Video was DVD. The audio was MPA (Mpeg-1-layer2). I am sorry if this is not what you were asking, I am only new to this forum so just finding my way around. Many thanks.
