While I am still having trouble seeing the Chroma Bug with the 45A (I recently looked at Toy Story Chapter 4, and man, it still seems pretty subtle on my rig) I did see a glaring problem that I think is also addressed in the Secrets write up.
What I think I am seeing is called combing, and it is NOT subtle. What is odd is that I have watched hundreds of discs with this player, and this is the first time I have seen this, and thus far only with one particlar disc.
The disc in question is 101 Dalmations II, Patches Adventure. While watching this disc, I see moments where certain sections of certain scenes show huge horizontal line stucture, and then it goes away. This happens throughout the entire disc.
I wish I could post a screen shot, but if you have this player, and have this disc, you will see it (assuming your player and mine have the same software, and Pure Cinema is turned on).
Right at the start of chapter 2, the dad walks through an open doorway....his shirt will suddenly have horizontal lines across it. In Chapter 5, there are some poodles that jump around...there are all sorts of horizontal lines that appear, and then clear when they stop moving.
What I have discovered is that the problem seems to relate to 3:2 Pull Down (Pure Cinema in Pioneer speak). If I turn off Pure Cinema, that problem goes away.
One good thing about the 45A is that there is a flag that appears when you turn on the disc display (where you see elapsed time, sound format, etc.). It sets a # in the display if the disc is flagged as Film based.
On this disc, that flag is constantly, erratically turning on and off. And what I have noticed is that when I see the combing (assuming that that is what I am seeing), it turns off.
I checked a few other titles, and found that in some cases (Hunchback of Notre Dame II) the flag does toggle, but in a somewhat consistent pattern, and I never see combing on that disc. I also popped in Apollo 13 and found that the flag was constant (the picture looked pretty good too).
I know the Secrets write up said that this player was a flag reader, and that this was NOT a good thing with DVDs that were improperly flagged. I suspect I have found a disc that is seriously screwed up with regard to flagging, and it really shows this shortcoming of the player.
I hope Don peaks in on this and can offer a comment or two.
