/*!
Take a format string and expand escape sequences, that is sequences that
begin with %, with information from the current VCD.
The expanded string is returned. Here is a list of escape sequences:
%A : The album information
%C : The VCD volume count - the number of CD's in the collection.
%c : The VCD volume num - the number of the CD in the collection.
%F : The VCD Format, e.g. VCD 1.0, VCD 1.1, VCD 2.0, or SVCD
%I : The current entry/segment/playback type, e.g. ENTRY, TRACK, SEGMENT...
%L : The playlist ID prefixed with " LID" if it exists
%M : MRL
%N : The current number of the %I - a decimal number
%P : The publisher ID
%p : The preparer ID
%S : If we are in a segment (menu), the kind of segment
%T : The track number
%V : The volume set ID
%v : The volume ID
A number between 1 and the volume count.
%% : a %
