Well I answered your question in the other post but with an ED TV, it can only natively display a 480p signal, if you feed it the 480i signal from your 522, it'll upconvert it to 480p, on the other hand, any 720p or 1080i signal you feed it will also be downconverted to 480p. You should still have a pretty nice picture on HD channels but your not viewing true HD at that point...
