I just got my headplay today.  Love it!  Use it for soo many things.  The only problem I have encountered is when I hooked it up to my RCA output from my original NES system.  Its hard to explain what is happening, but s picture shows up with distortion and doesnt actually do anything, just a screenshot.  Is there a specific type of RCA output that is needed?  I know the connection on the NES works, since it works on my LCD tv.  Anyone else having RCA connection problems with any other devices?
