Just a stab in the dark
But I seem to remember that there is a switch to 'write source files' to the DVD.
Encore is then trying to write your finished DVD project AND the source files to the DVD - and there isn't enough room
I haven't worked with Encore for a bit but I seem to remeber having the same problem.
Hope that helps
