The DVDLab forum site had a post from "Oscar" the creater of the project and he posted:
"I am happy to announce that 2:3 pulldown is solved (this was the last thing to fix) so I guess in a matter of week the very first version should be out.

(Just finishing touch) "

So look for this new authoring tool soon.
