I detected no compression flaws, even in the smokiest and most complex sequences. The original mono track is used and though it isn't memorable, it more than handles the task. I was surprised at times with how clear this mix was, as many titles this old display a lot of harshness and distortion. The music is clean and loud, but never overpowers the other audio elements. The sound effects also come through well, though they don't have the punch I would have liked.
Dialogue is sharp and crisp too, no volume or clarity issues in the least.
Extras VCI Home Video has included some nice supplements with this release, including some cool classic television commercials. Also found on the discs is footage of Buster Crabbe's Olympic antics, still photographs, and a wealth of interviews with the man. A nice selection of bonus materials indeed, kudos to VCI for tacking all these on.
