Denon 2900 Multi-Region DVD PAL/NTSC Prog Scan. When switching over to Progressive Scan while watching DVD film the player inserts two thick bars down each side of screen. I have tried changing the aspect ratio from 16:9 widescreen to 4:3 but the problem is still present. I hope there is a solution, perhaps with firmware upgrade? I have not found this problem on any other thread. HELP No one seems to have any advice, should I contact Denon(UK)?
