Can I ask about C lines?
I succesfully input 2 different lines but the line has stopped appearing in the bottom left hand corner of screen when you select a channel I'm getting an x under the black hole vu box and it display the screen resolution then an x under that. Any help in what i can do to resolve. Just to add I have an 8 legged box in the other room with permission to run multi boxes off the c line and thats working fine.
