One good thing I liked about my Voco Pro mixer was the fact that I could have 2 video inputs and 2 video out puts - switched back and forth by a simple switch...Now that I am going to be STORING that mixer and using a dfx12 mackie which I doubt has any video capabilities . 
What is available or WHAT DOES everyone use when you have 2 or more video sources going to the same monitor or monitors.  Like in the event you have your cdg player , maybe a dvd player  etc.?  
is the answer just a simple A/B video switch from RAT SHACK?
