I have recently got a bluetooth earphone so I could listen music
from my phone. In the mp3 player manu when I select the file to
play music it asks "play by" - phone or a/v headset. The music
plays fine when I choose a/v headset in my bluetooth headset.

However, the problem is that the movie player does not give me the
same option of selecting phone or a/v output.
Is there any way to solve this problem?
