After my comment in the quality tier thread (I think) that Pi is hardly tier 0 material, having at least very visible banding (in not that many shots fortunately, since it's mostly sunny ), and overall not that impressive detail, I was confronted, and it turns out it's the problem with the 2D disc, which is much inferior to the 3D one.
Might have been nicely processed out in the 3d, hard to say, the fact is, the 3D is quite flawless in that respect.
Also resolution wise :||
So if you can request the replacement of 2D with a 3D, do it
Later edit: I've been informed that the 2D stream of the 3D disc has those 'changing' black borders on the sides like some other new 3D discs, which makes it not quite suitable for viewing in 2D.
I think a reissue of the 2D disc would be in order.Edited by someone else - 3/16/13 at 3:43pm
