Ubuntu seems to simply ignore DVDs while CDs open up right away. i have the DVDr, DVD+RW tools installed through apt-get, i'm using GNOME and Nautilus for burning. i little while ago, after i had taken a break from trying to fix it for a while, the pop-up randomly appeared saying i had just inserted blank DVD. i tried to burn something on it and nautilus tells me the DVD only has 294MB on it. i just purchased these, and even if they were in use they're +RW so it shouldn't matter. Does anybody have an idea what could be wrong? thank you in advance.
