With the latest beta patch and in my system:

Intel Core2 Duo E7500 @2.93 GHz
Ati HD7850 2Ghz
8 GB RAM

I must say that the TV system runs smoothly with ranging from 34/35 FPS max. (most of the times) to 19 FPS min. (only on rare occasions). The TV system pans smoothly on every occasion: With or without zoom, with manual or automatic panning and independently on what FPS I get.

BTW, I can only pan the TV system in elevation, how can I pan the TV in horizontal azimuth?

Also, where's the button to shut down the SA-8?
