Reading mini DVDs created by DVD camcorders.

Q: I have a Hitachi dvd video camera. It was filming on a dvd-r disk, and about half way through the disk I turned on the camera and got an error message. The disk wasn't finalized, as it was only half filled. Can CDRoller help to retrieve the video files?
Q: I was finalizing a DVD-R in my Hitachi DVD camcorder and received a disc error that was probably the result of a power interruption. What are my chances of recovering any of the material with CDRoller?
Q: I often get probs with the dvd-r disks I use in a sony camcorder dcr-dvd91, usually before finalising. Can your software recover data from these?
