DMA on DVD is IMHO normal. Any erromessages in /var/log/messages? I think, this 
is not a problem with automount (HAL/submount).

dmesg says:
subfs: unsuccessful attempt to mount media (256)
cdrom: This disc doesn`t have any tracks I recognize!


CD`s mounted succesfully.
DVD`s can be mounted manually.
but kde not recognize the dvds

if you insert the DVD, take a look at /var/log/messages and search a line from 
hal-subfs-mount with "registered at resmgrd and called(0) /bin/mount ...". 
Please add the full line to this bugreport. 

With which command did you try to mount the same DVD manually? please try also 
the displayed mount command from the line above manually.

hal-subfs-mount[11000]: registered at resmgrd and called(0) /bin/mount -t subfs
-o fs=floppyfss,sync,procuid,nosuid,nodev,exec /dev/fd0 "/media/floppy"

command: 
mount dvd


This is the line that is add to /var/log/messages when an dvd is inserted:
cdrom: This disc doesn`t have any tracks I recognize!

please add/attach the output of "lshal", if the DVD is in the device, to this 
bug.

This is really a littlebit strange , but is there no other line from hal-subfs-
mount? To mount a DVD as floppy is ....

This line is on 2places in /var/log/messages
There are realy no other hal-subfs-mount line.

lshal: See the attachment

Hm ... looks like a kernel problem, the DVD is detected as empty (isn't empty?). 
HAL never tried to mount the volume for this emty DVD.

see: 
[...]
  volume.disc.is_rewritable = false  (bool)
  volume.disc.is_appendable = false  (bool)
  volume.disc.is_blank = true  (bool)
  volume.disc.has_data = false  (bool)
  volume.disc.has_audio = false  (bool)
  volume.disc.type = 'dvd_rom'  (string)
[...]

The DVD is not empty.
It is an DVD from the Linux Magazin.

@werner: as I told: this is not a HAL bug! If the DVD is detected as empty, this 
is IMO a kernel bug/problem. This is also IMO not a subfs bug, because HAL never 
tried to mount this DVD with subfs because it's detected as empty.

Do you know how many bug I've to sort in for component Basesystem
and Network?
If you think it is a kernel bug then choose Kernel
as component.

Since a manual mount of the DVD is successful, I think the kernel is fine...

could you reboot the machine and insert the DVD and attach then the output in /
var/log/messages since the reboot.

see comment #12 and please test also with beta2 please

i will test this with the next beta. In holidays for 2 weeks.

Any news?
