I have a disc containing a movie (which I assume to be a copy) which will play on my PC but not my stand-alone player. When I run it through DVDShrink I get the old "Invalid DVD Navigation File" message. Is there anyway I can burn a new copy that will play on my DVD player?
Are you able to see what the file type on the disk are? this will help, in leading you to being able to do this
