Beelzebub, I haven't seen that filter before, but it's interesting. One has to wonder how consistent the spectrum of that filter is though. Were ROne still tweaking the Z3, I'm sure he might find that interesting. Still, since ROne has been able to reach D65 with the CC30R filter, I think that's as good as it gets.
Finalheaven, I hate to say this... but many of the halos in Finding Nemo are there on the disc itself. In the underwater scenes, there's an intentional halo around the fish, which gets thicker and more diffuse depending on the level of light cast on them. I think that's just a creative choice by the filmmakers. Also keep in mind that you're scaling DVD resolution to 720p, which can make slight edging/halos worse than on the source, depending on the quality of the scaler. Unfortunately, a lot of it just comes down to the fact that you're scaling up a DVD to a big screen.
However, since you're running sharpness at 0, you might be exacerbating any existing edge enhancement. DVE is near worthless for adjusting sharpness, because it's too difficult to see any actual differences as you adjust. AVIA, on the other hand, has patterns which make it readily apparent which frequencies are being enhanced by the sharpness control. I run my sharpness at -4, because that's where the Avia pattern shows no white outlines around the thicker lines and no graying of the thinner lines. Considering that sharpness is usually zeroed to the same standard on all the Z3s, your unit should be similar. Try dialing it back to -3 or -4, and make sure TRANSIENT IMPROVEMENT is off (because that setting will show some slight edge enhancement).
Unrelated to the above, I recommend that you set any controls (Brightness, etc.) on the DVD player itself to their factory defaults. The goal is to let the source pass as unadulterated and pure a signal as possible. The only reason I would use the brightness control on the DVD player itself would be if the player has a known problem with white level clipping from the factory.
To the person who noted the softness of distant shots in Attack Of The Clones: That's part and parcel of the MPEG compression on the disc. As beautiful as that direct-from-digital transfer is, the variable bitrate compression does have its drawbacks, which is what you're seeing with that particular disc. Distant shots with larger patches of similar colors are compressed more by the encoder, resulting in a softer and less detailed image. Not much you can do about that. As to HD football games: Again, we enter into a possible artifact of scaling. Most HD football is broadcast in 1080i, which is being scaled to 720p by either the projector itself or your HD box (depending on how you have the output set). Because of this, you'll lose detail on smaller stuff, but close-up shots won't seem as bad because the scaler is given more to work with. Now, it could also be macroblocking as enier said, which would result in pixelation following a moving object. Again, this falls back to being a compression or signal issue from the source, not necessarily an issue with the projector.
