Thanks for the reply. I will try the various modes tonight. Any documentation about what the modes mean? (Hotkey vs App command vs auto)
I don't need the green button to work in MC (i just want it to keep the previous behavior - green button = windows media center). I suppose i can disable remote control for jriver. But ideally i'd want to be able to use the remote for JRiver when I am actually using JRiver - e.g. only MC captures the remote stroke, but not the media server running on background. Is that possible?
Now the weirdest thing is when i am playing video in WMC, clicking "play" on the remote would start music playing from JRiver. That's very non-intuitive.
