@pakrat:
Sry, still the same error
EDIT: It's always good to never give up.

I've tried a bit more myself and now it seems I've got it. It installs from ISO, and the ISO is DVD9 Size.
Instead of removing all entries in the Media table I just removed the VolumeLabel from all entries and that seemed to fix (one of) the problems.
Now I just need to tinker some more to get rid of the french movies and language files. ^^
@Smurf Stomper:
Bring it on. ^^
