Yes, I am talking on the capture machine itself. The machine is running
the servicemanager with 3 video feeds (hauppauge cards) and an audio
RAT. The RAT is very responsive, the VIC is not. I have attempted to
adjust framerates from 20-30fps with no change in response time. VIC is
just slow. I am running a 2.4 kernel, but I noticed this same thing in
older Linux and VIC versions as well dating back to AG 1 days. It has
become an issue lately due to meetings that we attend being encrypted.
It takes forever to manipulate through 3 VIC windows to set up
encryption for every stream.
