DVD acess problems. IO error.

[Ricardo Cappellano]

Hi all! I'm using Kubuntu Feisty Faw with generic 2.6.20-16.

When I try to acess any file in any DVD-data disk or try to plays any DVD-Video, I got I/O errors. The device is being mounted okay (manually and auto) in /dev/scd0. On Gentoo 2006.1 (with 2.6.17-r8, with the device being mounted on /dev/hdd) it works.

Here's the output for 'dmesg':

Any idea? Sorry if it have already been reported.

Cheers!

its not a hardware detection problem, but if you could post the information from the instructions at https://wiki.ubuntu.com/DebuggingHardwareDetection this would be useful. thank you

Hello, sam!

The problem isn't hardware detection, since it does mount okay, but, when trying to acess any file in any DVD Midia.

Hello again!

Here's the log for dmesg on gentoo:

(see the attachment )

[pete (petehere)]

Seeing the same problem here in Ubuntu Feisty on my Dell XPS M1210 laptop.

DVD mounts, but fails to play. Trying to access it produces I/O errors in dmesg.

Totem says "Totem cannot play this type of media (DVD) because you do not have the appropriate plugins to handle it."

I can browse the disc in Nautilus, but when I double click on a .vob file I get the following error
Cannot open vts_01_3.vob
The filename "vts_01_3.vob" indicates that this file is of type "MPEG video". The contents of the file indicate that the file is of type "plain text document". If you open this file, the file might present a security risk to your system.

Do not open the file unless you created the file yourself, or received the file from a trusted source. To open the file, rename the file to the correct extension for "plain text document", then open the file normally. Alternatively, use the Open With menu to choose a specific application for the file.

Copy a file yeilds similar problems
$ cp vts_01_1.vob ~/
cp: reading `vts_01_1.vob': Input/output error

I've attached the files requested from the DebuggingHardwareDetection wiki page.
