So I was finally able to get this burned late Sunday night, but I'm just getting over the flu from this past weekend so I haven't had a chance to write up a full review of the project just yet, but thought I'd highlight an important issue.
Someone can correct me if I'm wrong, but this project will not fit onto a 50gb bd-r in its current state. Using imgburn to calculate the file size, with the bd-rom content the project sits at 105% normal capacity. With the bd-rom content removed it sits at 104% normal capacity, so in order for this disk to work something must go. I had to rebuild the project after cutting out the French audio track. With only that language option removed and no other content, I filled 96% of the disk and the project worked.
I hope to have a more thourough review this weekend, but for now, people interested in this project will need to rebuild it without 1 of the audio tracks for it to work.
