Query: Bad Picture

I already have 30 ARTHAUS Blu-ray disc, and I've never had any problem with any of them.However all the sudden Bruckner 7th of Cleveland's picture quality is horrible.The lines are jagged everywhere, during the whole 66 minutes.The whole disc is like an upconverted SD.Although in the bonus part the quality of the picture of the inserted short concert's excerpts are good, so there was nothing wrong with the recording, but possible with the manufactoring.I hope that they are gonna withdraw this shoddy goods, and revise it.
