I'm having a weird issue watching the DVD series Oz on the Oppo 103. I have the resolution set at Source Direct but it is stretching the 4x3 screen to 16x9 making the people on the video too wide. Why is the 103 doing this if I have it on Source Direct? Shouldn't it be giving me the original DVD video? When I change the resolution to 480p then it shows the correct 4x3 aspect ratio.
Do you have the player set to WIDE/AUTO?
Try that; I don't use Source Direct so I forget if the player's aspect control works for that setting. I actually think it should not (Source Direct should mean you want all such processing down elsewhere) but other players have enabled it anyway.
