Hey, I have the same problem and when reading around in the forums, there are many others also with the same issue, i.e. burning DVD DL (xbox360) and getting i/o error, write error or whatever, in the middle of the burn! I have still not seen any good solution for it though. Some say it works after reinstallation of Windows, some say try to change to PIO-mode, some say you should switch to CloneCD and/or ImgBurn (same issue for me) or change DVD media (I use: Disc ID: MKM-001-00, Book Type: DVD+R DL). This drives me crazy, gaaaaah! For me, it sometimes works, perhaps once out of three, but damn it'll be expensive in the long run, right?
Right now I'm reading that one guy removed his nForce2 ATA drivers, could that have something to do with it (because I have a nForce2 400 motherboard)?
ANy help or suggestions'd be greatly appriciated.
