It's a DVD-R disc, but I have no idea what type of data it is. No files can been seen in the explorer. The DVD in unreadable, both in my PC and with my Panasonic home TV harddisk recorder unit.

When I look at the DVD info box in Nero, this is what I see:



I also thought about creating this backup, but since I cannot see any files, there is no way to do this I guess, except maybe a sector per sector copy, but I know of no program that can so this for DVD's. This pretty much will be a one shot chance only I guess...
