Naming miscellany:

GRACENOTE / CDDB fetched:

"Persian (Farsi) Level 1 Unit X" (for level 1)
but:
"Farsi Level 2 Unit X" (for level 2)
"Farsi Level 3 Unit X" (for level 3)

Also, they get the Disc # wrong for:
Level 1 Unit 2 (they call it 1 of 4 instead of 2 of 4)
Level 2 Unit 2 (they call it 1 of 4 instead of 2 of 4)
