Query: The Black Sabbath Story

I purchased this on VHS in 1992 (Released by Castle Communications PLC....2 X videos CAT No. SVO994 (55 minutes long) & CMP6070 (60 minutes long)) and the DVD is 85 minutes long??? - go figure, sounds like the DVD is just a rehash of the VHS with bits left out. This would be a great collectors item if it had full versions of the songs instead of small bites.
