Larry, thanks for your reply and I understand your comment. What prompted my question was a discussion (probably on an Oppo forum a long time ago) about upscaling when the majority opinion then suggested using the device (TV or DVD Player) that would best display standard DVD content. If I recall correctly, I thought that the general consensus was to not use the Source Direct or Auto option on the Oppo setup menu. I'll try Source Direct for while and see if I notice any differences...
