216 %A : The album information
217 %C : The VCD volume count - the number of CD's in the collection.
218 %c : The VCD volume num - the number of the CD in the collection.
219 %F : The VCD Format, e.g. VCD 1.0, VCD 1.1, VCD 2.0, or SVCD
220 %I : The current entry/segment/playback type, e.g. ENTRY, TRACK, SEGMENT...
221 %L : The playlist ID prefixed with " LID" if it exists
223 %N : The current number of the %I - a decimal number
224 %P : The publisher ID
226 %S : If we are in a segment (menu), the kind of segment
227 %T : The track number
228 %V : The volume set ID
230 A number between 1 and the volume count.
