More importantly, with the exception of some odd, early, and now discontinued plasma models, NO flat panel or fixed pixel display devices "do interlaced". That is, although you can feed them an interlaced signal like 1080i60, one way or another it has to be converted, or "de-interlaced" into a progressive stream, and then scaled or mapped to the device's native resolution, whatever that may be.
You have no choice. It's either going to happen in the TV itself, or in the disc player, or in a processor in between, but make no mistake: if you are watching 1080i60 on anything other than a CRT, it's being de-interlaced.
