50fps problems

Hey,

i have trouble, syncing footage of a FS7, a FS5 and a Nikon D750.

All three cameras Shooting in 50fps and our Avid MediaComposer 8.5 (on Windows 7, we dont use Mac) with a 25p projekt wont sync the footage.

The tentacles are on 25fps and Avid produce some errors douring the “read Audio timecode”-workflow.

(this error are also in a 50p project)

Are the tentacles designed to shoot in 50fps? I thougth, setting them to 25p should work fine.
