I recently (just before Christmas) purchased a Sony DVP-S735 DVD player. As I have not yet got round to buying a surround amp and speakers, I'm currently using my Hi-Fi, or the TV only, for the sound in stereo. I have noticed that when playing almost all DVD's, at certain points the sound seems to fade or drop out a little. It seems like the voice channel is getting overwhelmed by other sounds - particularly in intensive action scenes. This is repeatable, i.e. if I go back to the same point in the film, the same sound fade out occurs. The sound does not go completely, it just mutes a little, but noticeably so. Surely, if I have set the DVD player to 'Surround Off' or 'TV Stereo' modes, this should not happen - but it does. Do you think that I have a fault with the player? Any help would be greatly appreciated.
