I DO NOT RECOMMEND THAT YOU TRY THIS THOUGH i did not either yet. -- Cannot mount media in DVD rom drive, Acer Timeline 4810T. Drive is detected, and media only detected if placed in the drive when machine suspended. Even then DVD movies (purchased) are not recognised - error message that media is unknown. Audio cd's sometimes play. When trying to unmount, I am asked for my password - message given that another user mounted the media. https://bugs.launchpad.net/bugs/412527 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
