Queen A night at the Opera DVD Audio distortion

Has anyone else encountered significantly distorted treble on the video of Bohemian Rhapsody?
I think that may be in the master tape- I have the DCC gold redbook version and noticed the same thing, it so bad that I can't listen to the CD any more :( its a real shame because the music is soooo good.
They over-dubbed that song so many times (hundreds of times) they almost lost the original master. I will need to listen to it again (have not listened to A Night at the Opera in ages). Distorted or not, still great music though.

Well, the odd thing is that the non-video 5.1 version does not exhibit the same problem. Hmmm...
