Can hear music i.e soundtrack but no voices. I am a cab driver and would like to listen to my portable dvd player through my car speakers. The car stereo is only radio/cassette so i bought a tape adapter that can be connected to any mp3 type device. When i connect it to my phone the sound is fine but when i tried connecting it to my dvd player all i hear albeit very clearly is the background music of the movie i happen to be watching and no dialogue? Any ideas? :sigh:
