I have trouble to burn a blu-ray, error code 0

Hello,

I have edited a movie in final cut X, after 20min a would like to make a blu-ray to see the result on my HD TV.

It renders en make the files (H.264 + AC3) The burn program come up's, en note that there is a blu-ray disc en ask to delete all the data of the disc before writing. I click "yes". After a well the process stops with error 0?? Lack off disk space. I have 400GB free, and its a clean 25GB Blu-ray disc. If i check in the finder, my disc is created end named en if a open the movie with VLC it plays perfect! If i put the blu-ray in my PS3, nothing happens!

If i make a blu-ray disc image, sometimes it go to 95% end stops. Otherwises i get the full disc image. If i write this with toast, i get 2 black bands on my HDTV, end the movie is stretched. Al the settings are correct.

If i make a movie with the same project but delete everting exept off 5sec. Everthing go's perfect en i get full screen image on a SD card inserterd on PS3

-I try to make a new project en copy my projectfiles

-I duplicate the project without render files

-I make a fresh start with the same footage

all the same result! This on lion(external disc) end 10.6.8

I think this come's doing the update tot 10.0.3???

please a need help with this?
