Mediaplayer problem

I hope somebody can help me with my TMediaPlayer problem?
I am only 16 years old and do not have much experience.

I want te retrieve the track length of a CD track in minutes and seconds and
I want to play just one track of the CD, after which the playback of the CD
Audio will stop. How can I realize that? I hope (and I am sure) that someone
has got the answer.
