[Bug 579282] [NEW] Optical disks unmount during playback and are no longer mountable

Everything worked in 9.10

Upgraded Ubuntu 9.10 to 10.04.

when computer is first started and a disk is inserted the disk mounts
and begins play back fine.  Between 1 - 20 min later the video freezes
up or I get a message that says that the disk is not available.  After
which point the disk in the drive is no longer detectable.  I can remove
the disk and inset it again however it is not detected by the system
until I reboot.

I then tried a fresh install.  Downloaded the iso from the Ubuntu web
site (US location) last night 5-10-10.  It has the same issue.

I am trying to watch a movie from start to finish.

the drive should not be "un-mounting" during playback.

Any help would be greatly appreciated.

I can provide further info just let me know what is needed.  I'm new to the Ubuntu world so use little words please! :)
