one way is to copy and paste the .vob files from the DVD onto your hard drive, then rename the .VOB extesion to .MPEG, for example: RENAME VTS_02_2.VOB TO VTS_02_2.MPEG
Now you can import the file into Encore, not to sure on how you want to re-author the file by the way of chapter breaks?,as Encore is not an Editor. Pointless in adding chapter markers to the file as Encore does not support “end actions” for chapter markers
