Problem with brightness changing from light to dark to light every few seconds on bright sequences on some DVD's (eg. Toy Story, Incredibles) but not others. All are region 2. Using old Philips Combi TV, though don't get this problem when playing Freeview or VHS through it. Tried different wiring configs. including SCART direct into TV. DMR works fine on a mate's set-up, although colours look quite a bit different. Does the Philips have some weird fault or is there a magic set-up fix on the DMR. Thanks.
