OT: Processing video signals as audio?

["Jesse Ray Lucas" <jlucas@neoprimitive.net>]

So I had this idea the other night to take a video signal and run it through some audio processors, but I didn't know if the signal would damage devices meant to process guitar level signals. 

 

So I got the most disposable pedal I had (Boss Distortion) and ran the composite video out of my DVD player into it, then out of it into the TV. 

 

This resulted in a blank screen. 

 

Very exciting. 

 

If it would have been a flanger or a chorus would it have made any difference, or are the signals so completely different in nature that nothing is going to come out of it? 

 

If I would have ended the connection by plugging the out of the distortion pedal into a speaker instead of a TV, would I have gotten a sound?  I dare not go futher until I know whether I'm going to destroy my effects processors. 

 

Please advise, o wise list subscribers.
