WRONG! Video VERY MUCH cares what type of cable it's run down. If it's not run down cable with the correct impedance, it can be very, very unstable. Can you run video down standard audio cable? Sometimes. I was on a national tour that used plain vanilla BNC to XLR adapters for video monitoring and it did work. Sort of.BNBSound said:You should be able to buy or build a simple adapter to get it done. Video signal doesn't really care what type of wire it's on. Modulated signal does, but not AV. So if you need just video you could use adapters to go through the 1/4" or XLR lines on your snake. If you want audio too, build an adapter for each end that puts video on pin 2, audio on pin 3 and both share a common ground on pin 1. Should work fine.
Again, this is NOT CORRECT, unless I'm misreading and you had it done with the appropriate video grade coax cable (in which case it's just plain out silly, since there's no gear to connect it to with an XLR, and putting it down a standard audio snake is, as I noted above, not going to work reliably).
