I have found people with this problem but no suitable solution yet.

I'm running slack-10 with xine package. I have installed libdvdread, libdvdnav, and libdvdcss. xine check indicates that everything is "good". There is no problem playing vcds.

Yet, xine spits the dummy when I try to view a dvd.

error popup says "there is no input plugin available to handle `dvd:/`Maybe MRL syntax is wrong or file/stream source does not exist"

xine log viewer says input pluin cannot open MRL [dvd:\]

commandline output indicates that "can't seek to block 32", if I can figure out why I'd probably be close to a solution

ibdvdnav: Using dvdnav version 1-rc4a from http://xine.sf.net
libdvdread: Using libdvdcss version 1.2.8 for DVD access
libdvdnav: Can't seek to block 32
libdvdnav: Unable to find map file '/home/rick/.dvdnav/.map'
libdvdread: Can't seek to block 256
libdvdnavVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.IFO failed
libdvdread: Can't seek to block 256
libdvdnavVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.BUP failed
libdvdread: Can't open file VIDEO_TS.IFO.
libdvdnav: vm: faild to read VIDEO_TS.IFO

Can anyone shed some light on this

TIA

Make sure you can access /dev/dvd as normal user. Usually adding yourself into disk group is satisfactory.
Ciao

did you find the solution to this problem ?

chmod 777 /dev/dvd works also

I am now running slack-10.1 and xine worked ok with a dvd without anything needing to be done. Annoyingly I can not say why but here's some general notes about my situation.

I am running a 2.6.10 kernel I compiled with some things different from the 2.6.10 kernel in /testing. These changes include compiling in alsa, my sound card and some modules for dvb-t.

I did not deliberately do anything in the kernel config which I think would have an effect on whether or not xine plays dvd's.

That being said it may have had something to do with the fact that 2.4.x and 2.6.x handle devices differently.

Also Last time around i had installed libdvdnav and libdvdcss which are supposedly required to run dvd's and use dvd menus. I wasn't sure I installed them but I just checked and I do not have them on board yet I can do both.

That error always means that xine cant read the dvd becasue of permisions, or becasue you forgot to put a dvd in the drive.

This was perhaps an inelegant solution, but it worked for me

I had the following problem with XINE in Fedora Core 3:

error popup says "there is no input plugin available to handle `dvd:/`Maybe MRL syntax is wrong or file/stream source does not exist"

xine log viewer says input pluin cannot open MRL [dvd:\]

I created a soft link in /dev

#su
#cd /dev
#ln -s hdc /dev/dvd



go easy on me, I'm a

ln -s /dev/hdc /dev/dvd worked for me for a while, then it stopped working.
So I did ln -sf /dev/cdrom /dev/dvd
and xine plays well.
