145 begin with %, with information from the current VCD.
146 The expanded string is returned. Here is a list of escape sequences:
148 %A : The album information
149 %C : The VCD volume count - the number of CD's in the collection.
150 %c : The VCD volume num - the number of the CD in the collection.
151 %F : The VCD Format, e.g. VCD 1.0, VCD 1.1, VCD 2.0, or SVCD
152 %I : The current entry/segment/playback type, e.g. ENTRY, TRACK, SEGMENT...
153 %L : The playlist ID prefixed with " LID" if it exists
155 %N : The current number of the %I - a decimal number
156 %P : The publisher ID
158 %S : If we are in a segment (menu), the kind of segment
159 %T : The track number
160 %V : The volume set ID
162 A number between 1 and the volume count.
