My Denon DVD player directly connected to my 42" Sony Plasma via HDMI often has the obvious brightness popping of Macrovision.
Why?
I have not tried the component connection yet.
(I usually only post in vinly ot general... but this is a video problem.. thanks

Hi. I have both a 5910 and a 3910, and both connected to Sony lcd and plasma via HDMI without any problems at all.
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.
Called my dealer and got nowhere.
Finally from reading various things I decided to see if the problem was with rescaling.
Yup.
With the Denon DVD2910 output set to 480P and using the HDMI the macrovision problem disappeared. (with the exact same DVD Little Shop of Horrors musical)
I've been reading about HDMI as well and continue see short blurbs in magazines about various incompatibilities and quirks. My plasma and Denon 5910 have the older DVI interface and I've been able to uplscale DVD's to 720p or 1080i with modest gains in picture quality over 480p - and no unusual artifacts.
.
I've been following the spec, and it's got so many covoluted solutions to self-imposed problems (mostly encryption/DRM) that I think it's doomed. They're already up to 1.2 of the spec, mostly for bugfixes, and there are several more major revisions in the pipeline, which won't necessarily be backwards compatable with the current implementations.HDMI is what happens when you have design-by-committee, and best engineering practices take a back seat to protecting against 'threats' that the business hacks think are important.
/*Music is subjective. Sound is not.*/
I have a 3910 and if I run the HDMI to my Sharp projector (Z10000) I noticed that any resolution above 480p results in lots of onscreen video noise. A local dealer said that this is an artifact of the HDMI protection scheme.I ended up going back to the component output fed into a Runco DLP scaler -- gives me 720p and a really great picture (much better than the 480p from the Denon via HDMI).
