There are some abbreviations on the special site codes page of the wiki that I don't know in which situation I need to include these, or simply don't understand:
1. High Sierra Volume Descriptor
2. Multisession
3. DMI
4. PFI
5. SS
6. [T:BBFC] # Actually, I provided this information before: http://redump.org/disc/28488
7. [T:DNAS]
8. [T:PPN]
9. [T:VFC]
10. Compatible OS

1. High Sierra Volume Descriptor = PVD specifically for discs that use High Sierra rather than ISO or Joliet. Put into comments for site limitation reasons. 
2. Multisession = Session information on CDs that confine (or just use multiple sessions in general) to the Blue book standard. These should pop in automatically if using MPF though.
3. DMI = Disc Manufacturing Information. Metadata that we hash on Xbox discs
4. PFI = Physical Format Information = More medatata hashes. Again, used on Xbox discs
5. SS = Security sector = More Xbox related hash stuff. It and the above should pop in automatically when using MPF.
6. [T:BBFC] = Registration number for British Board of Film Classification (Used on UK discs)
7. [T:DNAS] = ID found on some PS2 discs
8. [T:PPN] = No idea actually
9. [T:VFC] = Same as above. Think it's some other Rating board ID.
10. Compatible OS = Not used
