After spending some time authoring a DVD with this package, I find it won't compile.

Brings up an error box saying 'File not found, Stop loading the project ?'. You click through 4 of these and in the compile monitor window it says :

Compile Error : No Video Stream Found
Build Cancelled

It is a simple project with 2 movies, 1 chaptered, 1 not. It has 2 menus, 1 as the first play, and one as chapter selection for the chaptered movie.

Any ideas anyone ?
