I think I’m OOTL. An ant-fascist statement from them is wonderful, but what is their association to the Potsdam incident referenced in the statement?

Edit: is it just that they are a German company?

I’ve been ripping DVDs for several years now and have never seen this issue. What program did you use? I thought most retail DVDs were read only once shipped, so I am not sure how you could corrupt it.

Have you tried playing it in another player (like a recent game console or a Blu Ray player)? It could be a corrupted driver for your PC’s disc drive.
