DVD Unreadable - Kinda... Help please?

[ariallen]

So I have a bunch of DVD+R's of home videos that are being read as blank discs by my Macbook Pro. I know there is data on it, because I can see the burn on all of them. I read that these media is junky CMC MAG/E01... but using some terminal commands, I think there is data on here after all.

So from this, it looks to me like there is 03:31:47 of footage on there. Two tracks (1 reserved, 1 "blank"). The blank one has a size of 2279216*2KB... which makes me think its just unfinalized. But when I go to do a dd to copy data to a vob or iso on my harddrive, I get an Input/Output Error.

Any ideas anyone? These are the last surviving copies of this footage so I am really hoping its not gone forever!! :-/
