"Deep Red" Problems?
 

I was watching my Anchor Bay DVD of Dario Argento's Deep Red, and I noticed something odd with the video. Towards the end of the movie, when David Hemmings is climbing the outside of a house, these faint, weird circles began appearing on the right side of the screen. It looked almost like film negatives running vertically.

Anyone else notice this?

Thanks

Maybe some kind of print damage? I never noticed it on my disc, but I'll take a look next time.
