Is there any way to salvage this DVD series?

[franciscola]

Some time ago I bought the English-language version of the 1989 Japanese/Chinese documentary series The Silk Road, only to later find out that the video is the worst I've ever seen on a DVD. It looks like there are two videos one on top of another and they're synchronized a half a frame apart, so instead of motion being frame-by-frame it looks like one half moves in one frame and then the other half in the next. I've attached a sample (the entire 12-part series is like this). Is there any way to salvage this monstrosity or should I just toss it? It's somewhat rare and not cheap but there's no way I can watch it in this sorry state. I can't believe that something so broken was published in the first place.
