Macrovision is not what's affecting your picture. Why? Because Macrovision only affects the analog outputs of your DVD player -- not the digital outputs.

For the digital outputs, if there is a Macrovision signal recorded on the DVD, the player will output an HDCP signal (High-bandwidth Digital Content Protection) along with the digital video. Not all player/processor/display combinations work as intended and it's possible that the Denon/Sony combination may not be 100% compatible (most incompatibilities resolve around how often the source device "polls" the recieving device via the HDMI/DVI connection). However, as the problem goes away at 480p, this is probably not the case as it's basically the same HDCP encrypted signal via HDMI regardless of the output resolution -- unless, of course, Denon turns off HDCP at this resolution. That would then explain why the two get along at 480p, but not at other resolutions.
