I haven't been here for a while and just checked it out on a lark. To clarify some questions as far as I know.
I converted BE from PAL 25 fps to NTSC 23.978 fps with slowed down audio and completely recreated the menu structure/authoring from scratch to replicate the PAL original. The extras were all converted with the speedup intact.
Boon converted RTJ single layer using the original soundtrack and speedup. I converted the PAL to NTSC with slowed down audio on a dual layer. I used Boon's authoring for the menus and just inserted my feature conversion.
I got half way through the sound post-correction on the Miami cut and just got sick of listening to it for the 100th time, so I stepped away and honestly forgot about it. I'll have to check if I still have it and see it wasn't on the hard drive I lost.
I never got a copy of the Miami BE PAL.
