Sin City audio hum

[Vidya]

I recently got to view a friends copy of Sin City. We watched the Theatrical release, and for the majority of the movie, I could hear a faint hum (specifically during dialogue). To me, it sounded like a problem with the source, not his system.

I'm thinking about picking up the movie, but I was wondering if this hum is present on the recut version of the film (the one that is seperated into episodes).

Thanks
