[Bug 412527] Re: 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.

[executorvs]

also bios 1.33 and lucid current on updates on a 5810TZ.  The settings
in bios don't nor have they ever fixed this problem. only using command
line to operate the drive or suspending and resuming to remount it if
you hit the button without thinking.
