I will, for the sake of what I'm writing, assume that you are copying the movie only, then converting for pvp. I will also assume that the rip before the conversion is also done by DVDFab, to remove the copy protection.
First, please advise the version number of your 'latest version' (some have said the same thing and on closer inspection, turned out to be using an ancient version)
Also, I assume you are using the PAL version of the film, which shouldn't be an issue, but the UK release may differ from our N.A. release in content and content placement on the DVD. (This shouldn't be an issue, but I'd better cover all the bases...).
Please advise and we'll go from there.
