TMediaPlayer does not support what you are looking for.

The MCI API, on the other hand, has an MCI_OPEN_TYPE_ID flag available for
the MCI_OPEN command.  That flag will allow you to specify the index of the
specific CD-ROM drive that you want to use.  You can use the MCI_SYSINFO
command to determine how many CD-ROM drives are available to MCI.  If
successful, the MCI_OPEN command returns the ID of the device, which you can
then use to send other commands to that same device.

There is an MCI_SEEK command available for that.  Make sure to use the
MCI_SET command after opening the CD-ROM drive to set the device's time
format to MCI_FORMAT_TMSF (track/minute/second/frame).

You can use the MCI_MAKE_TMSF() macro when specifying time stamps to the
MCI_PLAY and MCI_SEEK commands.  Use the MCI_TMSF_TRACK(),
MCI_TMSF_MINUTE(), MCI_TMSF_SECOND(), and MCI_TMSF_FRAME() macros when
retreiving the individual values from time stamps that you obtain.

You can use the MCI_STATUS command to query information about the individual
tracks, such as their lengths.
