VCube 24/25 question concerning Movie conversion.

I have a 24/25 related question:

Project:
Mastering a 24 fps Movie (1 min Commercial) in an 25 fps 5.1 environment.

Setup:
Pyracube: Masscore & Vcube SD combined running in an 25 fps environment.

Problem:
Playing the 24 fps Movie in 25 fps causes VCube to interpolates cq timecorrects, cq "add frames to the movie", thus correcting the length. The movie is stacked with close-up dialog, spotfx, and frame accurate audiocuts. The 5.1 audio stems, Dialog, FX, Ambs, Music are neatly on the timeline. Stereo Branch is available on the mix!er.

Question:
How can I be sure that the VCube interpolation corresponds to the correct frame? AFAIK, I can't. Whatever I do, can't get it right in one converion, pitch/stretch/MPEX3, won't work.

Here is my Solution, but is it correct?

I set VCube in 24 fps. I leave PMX in 25 fps. I assign PMX as clockmaster en timecodemaster in Virtual Transport. I Perform regular mastering in 25 fps. And then perform the regular uppitch on the Master using pitch/stretch.

VCube running in 24 fps behaves normal. It is in sync wth PMX, not interpolating, and still displaying the correct length (1 min).

I think it works, but anybody out there finished this read and has a deeper insight?

In answer to my own question: Yes it works! VCube running "wild" in 24 fps can be properly synced to PMX running in 25 fps on a PyraCube! After the uppitch the project was correctly Dolby-mastered to the 24 fps movie.

Allthough I haven't got a clue how Vcube managed to display the Movie on my 25 fps T.V?
