sync problems due to FPS change

Hi Guys,

I’ve received an OMF of a short movie that was edited in Adobe Premiere.
During the video editing process they have changed the project FPS from 30 to 24.
For the sound to fit they’ve slowed it down by 20% with an internal premiere audio plugin.
This slowing down process doesn’t transfer with OMf,
so now i have out of sync project to mix :unamused:

Any suggestions approaching this mess?

Thanks!
Oren.
