A quick check with MPDCenter says:
Check for: 6933 - Spectral Starguider.mpd
True - Mirrored parts free.
False - All files have correct License.
True - All Name entries are like filename.
True - Is MPD filename OMR conform.
False - All filenames in the MPD are OMR conform.
True - ~Moved to parts free.
False - Unresolved references free.
Error in: 6933 - mm.ldr Filename without setnumber does not match file description.
Error in: 6933 - mm.ldr Filename not OMR conform because of the above error(s).
basically your scheme:
Code:
0 6933 Spectral Starguider
0 Name: 6933 - mm.ldr
is not correct. This has to be either:
Code:
0 mm
0 Name: 6933 - mm.ldr
or
Code:
0 Spectral Starguider
0 Name: 6933 - Spectral Starguider.ldr
