[MPlayer-users] chapter list bug

I believe I've found a bug in mplayer.  I'm running the following command to
get information about a DVD:

mplayer dvd://1 -dvd-device /dev/dvd -identify -novideo -nosound

The output of the command includes the number of chapters in the title, as
well as a list of chapter start times, as can be seen here:

CHAPTERS: 00:00:00,00:03:13,00:07:24,00:13:33,00:18:32,00:24:02,

That CHAPTERS list is supposed to be all on one line, but I broke it up for
e-mail formatting.  As you can see, there are 14 titles on the DVD, but the
CHAPTERS list only includes the start times of  13 chapters.  This
corresponds correctly to the first 13 chapters, but the start time of
chapter 14 is missing.  It begins at 01:09:57, which I know from manually
reviewing the disc, but I cannot find any reference to that in the mplayer

This appears to be a simple off-by-one logic bug.  Can anyone confirm?
