Anyone ever hear of a problem like this? A recent batch of S2D processed movies I sent to my nephew have a sound problem on ONE of his two DVD players. On his player any background sounds, eg. music, wind etc. play fine but there are no voices when people are speaking. All were AVI's that displayed in S2D as NTSC (film) with 48k sound (2 were AC3, 2 were mp3). I don't process any 48k sound. Unfortunately I can't reproduce the problem on any of my 3 DVD players and he lives a three hour drive away.
