I have not been able to read a DVD burned on another laptop of mine, I burned the DVD on my laptop because I was unable to burn the disc on this computer. I was using ImgBurn to burn an iso file however it failed with Power Calibration Area error, yet the same disc burned perfectly on the laptop. I have also tested the disc on another computer and it worked fine too. The DVD drive has absolutely no problem reading other DVDs burned by a manufacturer such as the re-installation disc. I have refreshed the driver by uninstalling it, as well as updated the firmware. The computer is a dell inspiron 530 running windows vista. Any help is appreciated as i am some-what experienced but how it could read manufactured DVDs but not burned ones is puzzling.
