No, I've finished with the mono mix for the time being. I've released a rough AC3 file for my ANH DVD and an NTSC speed version to go with Dr. M's DVD. It's a straightforward process to extract video from an existing DVD and author a new DVD with the mono audio, so I'm not going to do a whole new DVD. I would consider the rough audio track to be of academic interest only, just a bit of fun until a fully restored version becomes available (I've sent the uncompressed audio file to a restoration specialist to work with).
Not forgetting that Jedi/Feta and Tellan have made use of the mono mix in their own projects.
