Did I do a capture from the 704? That has some internal video processing that can't be switched off. I have music video discs that play fine on my 8210, but "smear" on the other two machines.
Even with everything switched "off" on the 704, I could see some ghosting going with hologram guy's head when he walks up to THX and SEN in the white void. It was even worse with the noise reduction circuits turned on with a test capture I scrapped.
