I've recently purchased a 2900 and am very happy over all, but as I was watching some video sourced material (Peter Gabriel Growing Up Live) I noticed some streaks running through saturated reds. Also noticed it on some of the Alien Quad supplements. I have not seen any in film based material, and am aware of the alt. flag issue. Is this a function of the Sil 504 chip, or the Mits. deinterlacer perhaps?
