Hi all, I'm after some help. I am doing a long dvd of our holidays. I completed about 10 minutes and because it is slow on computer I burned what was already done to see what it was like on tv. So far all good. so went on to add new material to existing project, it has been saved but now when I go to burn it doesn't burn any of the new material only the first 10minutes, any help is much appreciated, I know this is probably something basic, but I have spent hours editing, did a search but didn't see anything relevant, thanks Phill
