Please help: Blu-ray error - file error - video buffer underflows

Hi all,

Just got a new video editing system and Blu-ray burner and was very excited to test out Blu-ray burning. Unfortunately I keep getting the following error whilst burning my timeline:

blu-ray file error: file already exists - code 6 note: video buffer underflows

The timeline consists of just one AVC video track and an ac3 track.

Any help would be greatly appreciated!

Cheers
Ben
