Dunno, may be that particular movie compresses better than average one, but overall simple math is that mpeg 2 on 25gb media and especially with uncompressed sound on that does equal lots of artefacts due to insufficient space for video.
Morons using defective masters with scratches and dirt are different matter, but again, it's real frustrating to see that kind of mishaps happen on BD side only...
