OK well that worked.
Interesting collection of clips
You're not doing what I thought but I think I understand what it is that you are doing.
To be honest I don't know what the problem is other than this:-
#248 Text 0 File BurnAtOnceRecorder.cpp, Line 1834
DVDEngine Failed to write buffered data of length 1 to sector 487264
but I have a potential solution.
Change the output device to image recorder & create an ISO image - hopefully you're using NTFS as the file system - & then burn that image seperately. I'd use ImgBurn for this rather than Nero.
As these are clips that you don't expect to view again why not just create a data DVD rather than a movie.
Also unless you really want to use it , uninstall INCD as it tends to cause a lot of people problems. Personally I wouldn't have it near any of my systems.
