Up to date, my problem was with 4 finalized Memorex DVD-RW from my PVR (Samsung DVD-R120)

Hmmm, I try with a DVD-R recorded from the same PVR, I got the message "cannot read super block" in konsole when I try to access the media. In this case, auto mount haven't mounted the drive, I do it manually.

I try also with an unfinalized Sony DVD-RW and got the same result as the 4 Mawell. Auto mount worked well.

Note: I have passed udf_tester(udfct_1.2r2) on the DVD-RW and it sees the UDF 2.0

Here's an extract of udf_tester result:

Other ideas?

I'm thinking that the permissions may somehow be linked to DVDs themselves, since they all come from that PVR.

Yes, it's a possible. I don't have the UDF knowledge but i have downloaded the specification from OSTA's Web site.

If UDF have his own permission, is there a way to ignore those permission when mounting the media.

Another track i will explore, it's HAL to see if the mapping hardware/specific driver(or config) is OK. I have a doubt about HAL because DVD-R media isn't recognized.

Regards

Ben

I am just suggesting you might try a CD in that drive, or a data DVD. Something that didn't come from the PVR.

Data DVD and Data CD work perfectly. i.e.: I use a Mandriva DVD image to upgrade from 10.1 to 10.2.

Ah. So it's just the particular ones burned with your PVR? I can't imagine udf actually having a permissions setting. Hrmm, I'll look into it and post back here if I can find anything.

I don't know if it's limited only to the one burned by my spcific PVR (Samsung DVD-R120) because I don't have other DVD-rw from other PVRs to test.

Here is the content of file "00macros.conf" I found in /etc/makedev.d/, I will googled to be sure if it's really THE PLACE to set what we are searching for. At first look, it's promising ;-)
#
# Generic permissions
#

=ALLREAD 644 root root
=ALLWRITE 666 root root
=FLOPPY 660 root floppy
=KMEM 640 root kmem
=PRINTER 660 root lp
=PTY 666 root tty
=ROOT 600 root root
=SERIAL 660 root uucp
=STORAGE 660 root disk
=BURNER 660 root cdwriter
=TTY 620 root tty
=AUDIO 660 root audio
=VCSA 620 root tty


# Define "console" as an alias for root for specifying input devices and such.
=CONSOLE $ROOT



#
# Sound devices major & API limits

=OSS_MAJOR 14
=ALSA_MAJOR 116
=MAX_CARD 4

Yeah, I just don't think this issue is systemic. If other optical media works, something must be specific to that media.

I think makedev, which the 00macros.conf file is related, is used for static mounting.

I'm looking udev, and try to configure a rules file for udev, in etc/udev/rules.d/ directory. I have created a file name 10-mdk.rules which should be read before the default file 50-mdk.rules.

I try to fing how to write the rules for the specific media, DVD-RW, not just for the drive "hda".

To follow...
