Thanks. I will be researching on this when I am home. At the time being, actually I used one of your old tools to extract the DVD Movies and they just play fine. Maybe there are some other tricks to achieve my goal? Nevermind, I am going to leave the disc and computer running at my office and come back to check tomorrow. Man, you are one hell of a friendly developer, aren't you?

Sorry to be triple-posting but I think each of the posts is with a different topic so I guess I will leave it be. If my hypothesis is correct, there will be no software on earth is going to treat the disc only by half and ignore the other half of the disc. If that is the case, is it possible to configure ImgBurn to create an image out of the first half of the disc and apply corrections to the second layer of the disc with empty contents? If it is possible, I think this will be the goal I am aiming at: Creating an ISO of a DVD-9 with only content of the first layer and empty content of the second layer.

Update to this: I just figured out the structure of the disc: VTS 1: 6 Chapters, some trailors and stuff VTS 2: 1 Chapter, something about opening logo VTS 3: 3 PGCs, the main movie - PGC 1: 5 Chapters, around 40 minutes, fine - PGC 2: 5 Chapters, around 35 minutes, fine - PGC 3: 5 Chapters, around 60 minutes, for each of the Chapter, it fails to read right from the first Sector. I am now having a hypothesis that this manufacturer might have put the content of a DVD-9 into a single-layered format while keeping the header of a dual-layer. Now, I think I should simply take what I can get and forget about the PGC 3. It probably is never going to pop out. Thanks.

Thanks. That was one hell of a confusing time it shows. I should probably try to read the disc with the other drive (in a computer bought in 2007). And aye, it takes me an hour to go home.

Thanks, Lightning UK, But I am not sure about this disc being 900-hours long. If it is a mere hardware problem, should it still return such a ridiculously long time for the disc? Would it be, by pure speculations, that this problem originates from the hardware but it is just that ridiculously wrong time that makes it impossible to read the content? Something about "the disc isn't that long but the programme tries to read that address" or also something about the switching of the layer? Besides, my drive in this computer is a really strong one. I had another disc that was read in another computer with more than 50k counts of error and got aborted. Then I made it to this drive and managed to read that disc with a mere count of under 200. So there is nothing else that can be done apart from using another drive? And... would it even worth a try to use that other inferior drive of my other computer?

Hi Lightning_UK, I have been admiring you for creating these tools for the world: the ImgBurn and the DVDDecrypter. But then I really hope to get some support for reading a DVD into an image. This DVD in particular has some very strange properties. 1. Whenever I get to around 50% of the disc, it gets L-EC uncorrectable error or unrecovered read error. 2. The properties: 2.1. Sectors: 4,085,791 2.2. Size: 8,367,699,968 bytes 2.3. Time: 907:59:16 (MM:SS:FF) (What? Seriously? A DVD with 900 hours? This time is shown in both DVDDecrypter and ImgBurn) 3. This disc is a disc #3 out of a set. The first two discs are normal and unencrypted. 4. The box says this disc is a DVD-9 5. The disc is a standard disc of DVD Movie. It stores the last three symphonies of Beethoven, which should not be more than 3 hours in total. (I think it takes around 2.5 hours) 6. I can play first half of the DVD in The KMPlayer but not the second half. Thanks. Attachment: Log
