initialising media player and combo box

[servalman]

Another stupid question

I have two media player components instance (media_1 & media_2)
What is played inside is choose by user via a two combo box (combo_1 & combo_2)

Question:
If media_1 is already playing and the user is choosing another media with combo_2 how do I
Reset media_1 and combo_1 to their initial wich is:

1) Nothing is played in media_1
2) combo_1 is set on default label

:D
Thanks A lot
