cant play dvd's

CRego3D · 09-30-2003, 05:40 PM

I have installed Suse 8.2 on a Fujitsu P2040

I set the dvd player as /dev/sr0

when trying to play a dvd I get this error

linux kernel: i/o error: dev 0b:00, sector 15997472
linux kernel: lost async page write due to i/0 error on 0b:00

the sector number changes

any ideas ?

is your dvd device using the block scd0? from what i've read, sr0 correlates to scd0 on suse. i'm not sure as i don't use suse, but what happens if you try to mount your dvd drive with /dev/scd0 instead of /dev/sr0?

I can mount the dvd using /dev/scd0 .. but xime or mplayer wont .. it says it can't open the dvd device /dev/scd0

oh that's easy. open up a shell terminal and su into root. create a link to scd0 (or the right device block for your dvd player).

ie.

ln -s /dev/scd0 /dev/dvd

that should solve your mplayer/xine problems. xine/mplayer by default look for a device /dev/dvd. creating a link called /dev/dvd pointing to scd0 solves this.

also, with xine/mplayer, you do not need to mount your dvd. just put your dvd in and press the DVD button on xine or mplayer.

no wont work

if I do the symlink to sr0, I get the same i/o errors, if I symlink to scd0 .. I get the "cannot open" error

when you create a link to scd0, what's the complete error?

cannot open ?

if it's the error i'm thinking of, it may be a needed library. you'll need to find a suse rpm of libdvdcss and install that. if you're not using the newer version of xine (it's at 1.0) you may also need to download and install libdvdread. if this is indeed the problem, it should solve the problem with mplayer too.

what DVD button on Mplayer ?
I have the default GUI and I don't recognize any DVD button ?

oh yeah. i don't use the default skin. i'm using the phony skin and it has a DVD button. but if you're using the default skin you should be able to right click on the player or viewer and from the context menu choose DVD > Open Disc

I've never had success playing DVD's from a scsi emulated device... is this actually a scsi device or a dvd burner? if not i'd remove the scsi emulation (hdc=ide-scsi in your grub or lilo.conf) and reload it to access it as a standard ide device.

if it is a burner you might feel brave and try a 2.6.0 kernel which supports direct IDE burning.
