was this tested on your unpacked DVD before it was run in PCGedit to create your fixed ISO because those 2 files will be slightly different before its run in that program to create the ISO anyway.

WOW but you're quick!

This was after two or three go-throughs with PGCedit. So what I'm inferring is that my slightly-off files weren't off after all. Just slightly modified in an expected fashion.

Good to hear that the one i posted and with the fix applied it all work ok. This fix is just for the torrents not the one off newsgroups

But hey! At least I'm no longer wondering if I could have accidentally done something wrong. The disc works, and works well, and I'm delighted to have the music-only track.

Thanks again for your patience!
