the inputs on the Panasonic plasma are weird... No matter what discrete you throw at it, it switches to video 1, and then you have to cycle it from there.
There's a set listed for them, but it's RS1994/OFA codes... you'll have to search the One For All area for them- look back like a year and a half ago...
We can do it my way, or we can do it my way while I yell. The choice is yours.
