I'm on the road at the moment and staying in a hotel that has the normal 20" CRT in the room. It takes a feed from Sky digital and low and behold, last night, I saw the blur on it, several times. So, as far as I am concerned, this is definitely NOT a DLP effect. However, because our DLP sets are so large and clear, the effect is definitely exagerated but not caused by DLP. Thats my final word on the subject (until my next one).
