Well, after using my steps to back up specific titlesets (see my other post), everything went well until mkisofs. I'm still scratching my head on this one...

Whether I access the burned DVD, or the ISO image via loop device, and play it with XINE I get BLACK subtitles... the words are correct but just impossible to read. However, if I mount the DVD/ISO and access the VOBs directly using XINE, it works fine.

I;m going to keep working on this, but if anyone has any ideas, I'm all ears.
