[Skunkworks] DVR video issues

Hi y'all, I have an interesting problem: I need to copy videos that were recorded on a cctv system. The videos are on two harddisks. Connecting the disks to a pc or via usb with an adapter & casing doesn't work. I was told the only way the videos can be copied is if they are in a DVR machine. The client I got them from is using theirs so I need to get me a temporary one to do the transfer. Can anyone assist? -- Mutinda Kitana P.O. Box 55141-00200 Nairobi. Tel: +254-722944455
