first i have win xp and my remote over hauppauge wintv nexus-s.
the most things works all right but by volume change left/right i have a big problem.
i have tried to set left/right on the standardkey of my remote but always if i raise the volume the balance goes right.
anyway volume left function has the same effect like volume right ,but the balance goes left.
edit: sry guys!
i've found out how it works.
not with volume left/right but with volume change (raise positiv number ,lower negativ number).
it was a little bit confusing because the german translation
in english its easier.
