johnny5 which dual layer DVD recorder do you have?, have you finalised the disc if its a write once...otherwise you could try clicking open files instead of open disc then browse your DVD disc and look in the Video TS folder and click ok.
It might be best to move selected vob files into a separate folder upto the 4.3gb limit and re-author using ifoedit for example, if your wanting to give that a try lmk and i will type it up.
