I need help sourcing out an A/V cable for the RasPi 2 B (or RasPi B+). The 4-pole 3.5mm plug to 3-RCA A/V cables I have lying around that came from our Sony Handycams were unfortunately incompatible. Sony's implementation: The GND and Video signal pins are interchanged.

The reference picture below shows the desired pinout:



An alternative is to find an equivalent Apple or Zune A/V cable. But again, I need help sourcing these out.



Thanks much!
