Thanks for all the help, the DVD player may have protection somehow. I hadn’t thought about that. Actually when I last did this back in 2008 on an older 2005 Mac in Premiere 6.5, it worked, but I was using a different DVD player then, so the DVD player having a copyright security feature maybe the issue.
Next I will try the method suggested of copying the .vob files from the VIDEO_TS folder, and putting them in Premiere. Actually, Lee my timelines are PAL (UK thing!) but I get your point. This sounds too good to be true but I’ll give it a go. I didn’t know you could do that. Thanks for your help everybody. I’ll let you know how it goes.
