That said, I've got a disc image of the Interaction Masquerade with titles for the show, childrens awards and adult awards. Each entry has a chapter mark (and there's even one to skip the music cue that was blown in the middle).
I've also got a disc image of "Ready! Steady! Sew" with chapter marks at reasonable points.
I've saved the projects; if there's anything else to add I can just tweak it and re-code the disc.
