3:2 pulldown is only selectable when 23.976 is your framerate.if 29.970 is chosen i can not use 3:2 pulldown.

Exactly, because that's what 3:2 pulldown is - a method of translating 24 frames per second into 30 without speeding up the film. To go from 30 back down to 24, you just need to remove the pulldown, or do an inverse telecine if the transfer was at 30fps to begin wtih (like your Volume 2 DVD).

(Note that, as I'm getting sick of typing 23.976 and 29.97 all the damn time, I'm rounding up to 24 and 30, even though neither one of those is entirely accurate.)
