Hi Polytropon, Thought I would put in my $0.02 here. Your not going to find a tool like this under FreeBSD or any freeOS that I know of. The issue is one of assumptions. The so-called "cheap DVD"s that you speak of which have bad sectors, in actuality do NOT have bad sectors - at least, not randomly bad sectors, that is. More and more commercial DVD's are coming these days with copy protection on them. When the video DVD is read as an ISO, the reader gets to a certain block in the DVD then commences to return errors. I am not sure how the video playing software gets around it but I suspect it sends a command to the reader. The only program I know of that reads these is a Windows program called DVD Fab. It's trialware, you can download it and run it for a month. It also gets around the known copy protection schemes used in BlueRay which are considerably more sophisticated. If you can make an ISO of a video DVD with this program but it fails using dd, then your dealing with copy protection. For example rental DVD's of Pirates of the Carribean 3 and Clone Wars both have this. I don't know if the versions you buy have this as well, I suspect they don't since my guess is someone is getting royalties on this scheme somewhere. I would love to see someone write some code to get around this for use with dd program. Of course, I know your NOT trying to illegally copy commercial DVDs so it's not necessary for you to reply with protests. Heh.
