I've made a patcher to fix the chapter problem (for Windows only). The executable file is very small (only 80KB) and will patch one of the VOB files to fix the chapter link. The only caveat is, you'll have to use WinRAR or something to extract all the DVD files from the .ISO image onto your hard drive, then run the patch (and then, if you wish, create a new .ISO image from the updated files).

You can download the file here: http://www.filefactory.com/file/da426a/ (40KB, zipped).

It includes an updated .NFO file with instructions to use the patcher, as well as a changelog.
