Not sure if the problem is my TV, my Xbox 360 or both. But I bought this cable because I wanted to upres my DVDs, and indeed it does work for that purpose. However, the quality of the picture, although slightly sharper than the composite cable, got weird and fuzzy. Might have something to do with refresh rate, I don't know.I returned the cable and am happy with my composite. I now use a HDMI DVD player to upres. They cost $50 on Amazon.
