Marvel G200TV - how do you identify early "bad" model vs. late "good" model?

[DAR]

I have read here that some early model Marvel G200TV cards had problems with TV-out image quality ("green tinge" problem), and that this problem was corrected in later model Marvel G200TV cards. I am looking to purchase a Marvel G200TV on the used market, and I want to ensure that I don't end up with one of the early "bad" cards. Is there an easy way to differntiate between the early and late model Marvel G200TV? Ideally, I am looking for a question I can ask a prospective vendor that will definitively identify whether the card is one of the early ones with the TV-out problem, or one of the later ones with good TV-out.
