As I saw recommended in other posts, I broke up my home movie into several clips. I edited each clip to my liking, and produced each clip into its own MPEG file.
Then I imported all the produced clips into a new project, which is intended to be the complete movie that I would burn to the DVD. I added a few small things, like chapter thumbnails for each clip, and also did some minor editing in the project.
The question is, do I have to Produce the combined video again, or can I just go to the Create Disc tab?
As a related thought, is it a bad practice to Produce previously Produced clips - i.e. will I lose video quality by the repeated importing and encoding?
