Mike,
I rarely trust the warning messages I see in software firewall anymore.
DInput.dll is part of Windows Media, so I think it trying to access it comes simply from the fact that it needs windows media for playback or processing.
What the firewall is saying is that another program is using a Windows Media’s component, but not windows media itself.
Why is it trying to connect to Internet, well that is strange indeed. Could it simply be trying to get outside info about the codec? .Maybe an email to the Gspot guy would tell us.
