Interesting this one! From a downloaded .avi file in full cinemascope (i.e. it's in 4:3 with thick BLACK bands top & bottom) when burnt to disc it has pulsation PURPLE bands at top and bottom beyond the balck ones when viewed on a TV. If I blow it up to fill the screen, the purple does dissapear off screen, but there is still a slight pulsing on screen. Any suggestions as to cause?
