Hi there,
I know what you mean. With our avant ( 32 DVD) we had the same problem - but there´s a possibility to solve: It´s a problem with the film mode.
Follow this guide to deactivate: (all with the Beo4 remote)
MENU --> SETUP --> 0 0 (sero sero) --> GO --> chose MONITOR --> PICTURE ADJUSTMENTS --> FILM MODE (<-- deactivate from AUTO or ACTIVATE)
Be careful - don´t change the other things, only the Film Mode.
Tell us, if the problem is solved!
regards, Adrian
