Frank, listen to the above sample when forced to mid-side coding.
This excerpt from "Main Theme", track 8 of Pink Floyd's soundtrack 
from the film More, will sound awful when there are M/S frames.
Even at 320 kbit/s you will easily detect distortions. This is
an example where all frames should be L/R coded.


Ciao Robert
