Can i split cable from WOW! Cable converter to 2 TVs?

I have two TVs next to eachother so I can have the tv on while playing PS3. Right now we have a normal 1 to 2 splitter to split the signal from the wall to each tv. With the converter box, is there a way to split the signal after it comes out of the converter? I tried it with the current set-up and it doesn't work. I get audio on one tv and both have scrambled picture. Is there a different kind of splitter that could work?
