Copyright info help please.

Hey guys, so I made a funny 30 minute long Youtube video consisting of the more bizarre moments of "Hell of The Living Dead" pieced together with funny commentary by me. Youtube has blocked the video due to a copyright dispute from a company called BuzzMyVideos Entertainment who claims to own the film. I'm disputing the claim, but this involves handing over my personal information to the group which make me anxious. Can anyone shed some light on who owns the copyright to this classic film?
Here's my video which is visible during the dispute process.
