[MPlayer-cygwin] VCD, different behavior

Hi. I'm developing a mplayer frontend (smplayer). I read that now mplayer on 
windows can play VCDs (vcd://...) so I tested it this morning with a recent 
mplayer build.

It works, but there are some differences compared to the linux version.

This is what mplayer under linux (MPlayer dev-SVN-r25184-3.3.4) says in the 
console output when playing a vcd:

Playing vcd://2.
ID_VCD_START_TRACK=1
ID_VCD_END_TRACK=3
track 01:  adr=1  ctrl=6  format=2  00:02:00  mode: 0
track 02:  adr=1  ctrl=6  format=2  00:15:21  mode: 0
ID_VCD_TRACK_1_MSF=00:13:21
track 03:  adr=1  ctrl=6  format=2  02:07:57  mode: 0
ID_VCD_TRACK_2_MSF=01:52:36
ID_VCD_TRACK_3_MSF=03:41:66

And this is what the windows version (MPlayer dev-SVN-r24956-4.2.2) says 
(using the same disc):

Playing vcd://2.
ID_VCD_START_TRACK=1
ID_VCD_END_TRACK=3
track 01:  adr=1  ctrl=6  00:02:00
track 02:  adr=1  ctrl=6  00:15:21
ID_VCD_TRACK_1_MSF=00:00:00
track 03:  adr=1  ctrl=6  02:07:57
ID_VCD_TRACK_2_MSF=02:15:21
ID_VCD_TRACK_3_MSF=03:07:57

You see, the length (is the length?) that appears in the ID_VCD_TRACK_X_MSF 
tags are not the same.

Another difference is that under linux title 1 is played with vcd://2, and 
title 2 with vcd://3 (vcd://1 doesn't play anything), while on windows title 
1 is played with vcd://1 and title 2 with vcd://2 (vcd://3 plays nothing).

This different behavior makes that my program doesn't work as expected when 
playing vcds under windows.
