It is very strong correlation for me between 2 channel and 6 (better known as
5.1 channel,
often for DVD-disk) or even more channels. Magic with my first example - it
re-route
6 channels to 2. And yes, it was the same problem on Linux for me (and for many
many
users. And trouble is worse for laptop users. But you know this).
I suspect that there is no problem on Windows platform because there is
automatic sound
normalization by players or Windows OS. And I don't see how to normilize sound
with mplayer
without re-encoding video clip with mencoder.
My settings, but there are no difference as I can say:
