I finally figured out the pins needed to get the Raspberry Pi connected to a DVD Slave display using a simple 4 pole 3.5mm connection.
The Pi is a Raspberry Pi 2 but should work with a B+ as well.
The display is a slave display for an Insignia Display, the NS-D7PDVD.
I purchased some 4 pole 3.5mm connectors from ebay and used a cable I purchased from Frys (SKU 6957167). The cable was kind of pricey at $5.99 but splitting it in half gave me two and saved a lot of time.
Also they cables were easy to use, no shielding.
Basically the Red and Yellow wires stayed the same but the Blue and White Crossed.
As for my workout, I tried to run a 1 lap today. Pretty bad time, but my knee was hurting.
Time: 19:19.62
I did do an extended walk afterwards.
