Pluggin straight into the TV. It's an older TV so it can only do it through one input, but yes, it says on the bottom Input: 480p and plays DVDs/Wii games with progressive on.
Its just at that one point: everytime I press 'Home' and then click 'Wii Menu' and BOOM signal is gone, goes to black. As soon as I say 'yes' or 'no' to 'Are you sure you want to quit?' the signal comes back.
I just took it as crappier cables/TV and just play 480i.
