Whenever you adjust ANYTHING in the pic adjustment menu, or want to stay in a user defined memory setting, you have to hit enter after you toggle it or it won't stay. So in this case go to the IRE setting and set it to 0 then hit enter on the remote. Then back out and see if it stayed. The 0 IRE also applies to the STD setting as well.
If you are running in DVI, make sure your black level in the DVI settings is in "Normal" not "Enhanced" otherwise you're clipping the below black information.
The macroblocking can be masked if you set your black levels a certain way, but they would be set incorrectly. If your black levels are set properly the artifacts are present with some material. Remember, the artifacts are actually part of the DVDs authoring, the Faroudja setting is just enhancing them exponentially so that they are blatantly obvious, where normally you may not see them at all.
Also, I have noticed that the problem manifests differently on different displays. I hooked up a 5900 recently via DVI to a 50" Panasonic plasma and the artifacts were extremelly bad, making anything just about unwatchable. I am talking huge amounts of blocking and large patches. But the day before I had connected a 5900 via DVI to a friends LCD PJ on a 90" screen and using the same material didn't see anything. The player still had the issues using certain test patterns, but nothing with the material I used on the plasma. This means that certain displays may also enhance the issue on top of what the player is doing.
