Hey George, As it happens I am a big fan of Canare cables. I used to work in a special effects house and we were advised to try this cable for our audio and video feeds. All of their cables I have tried are incredible, and I have used them ever since. I am curious about the use of vid cable. There just arent enough conductors to wire for balanced XLR. Sorry I can't really answer the 75ohm video cable thing, I'm quessing it has to do with impedance matching. They make a lot of different stuff and they definately make something that will work for you. Does bryston list a model # for the cable they spec.? I really like the L-4E6S cable for mic or line, balance or single ended. 4 twin helix conductors, a full braided shield and cotton filling. If you find out more about this somewhere else, please post, I'm curious now. Thomas
