Hi,
I use 2.6.9-ac3 on my Laptop and I just wanted to burn a DVD-Video with
my external Pioneer DVD writer which is connected via fire-wire to the
Laptop.
Before 2.6.9-ac3 I used 2.6.9-rc2-mm2 and with this I could write CDs/DVDs.
<rant>
So why is it still impossible that users can write CDs/DVDs. I, as a
user, find this rather ridicolous that you have to patch the kernel to
get this simple thing running. Security is important, yes, but this is
just annoying.
I really hope that gets fixed soon, because its just annoying to reboot
to a different kernel, just to write CDs ...
</rant>

It should work, are the permissions on your device file correct?

Make sure that cdrecord (or the analogous DVD burning utility) is NOT setuid
root and that you (as a user) have the write permission for the writer
device node.

Try with this debug patch so we can see if it rejects command it should
not.

I'm running a 2.6.9 vanilla and, as user, my toshiba DVD is correctly listed
by k3b... the only thing that sounds strange is an error saying it's
impossible to determine the supported writeing speed by the device

Security is important, there are no buts about it. See the almost
endless thread on this earlier. You can run your burns as root, of course.

I'm not sure what you consider "fixed" in this context, but if you mean
disabled security I don't personally expect (or want) that.
Someone claimed that cdrecord could get RR scheduling with attributes
set (did they mean capabilities?), but I haven't seen a working example
yet.

I added the patch again 2.6.9-ac6:
The strange thing is, this time I see a device, but its crippled:
k3b sees it as 7 0.62 1 /157 3474
But this device can not the DVD writer, because the dvd writer is on
/dev/scd3, this strange device above is on /dev/scd0. But still acording
to the settings, this device can burn dvds (Writes-DVD-R(W)s: yes).
So I tried again to start k3b as root, but this time the dvd writer
didn't show up anymore ... Somehow I get here very confused.
this is my dmesg output when I turn on my DVD writer

of course I can ... I can even start X as root if I set it up correct,
but thats not the point. The point of having a user, is _not_ to have to
start programs as root. I don't want that.
Sure its just my private laptop, at home, where only I work on, and its
behind a route. Still, I think that argument _does_ not count.
If its a security thing, and the client program hasn't adepted, okay,
but this ...

That was not my wish and I don't want that.

well I use k3b so it uses groisofs to burn dvds ... I don't care much
about cdrecord and in my deep inner world I hope they get replaced, by
someone with whom you can argue.

thanks I will check that out. But what I am more worried, is that I
don't even see the device ...

Yeah, just give a view up from what I tried today
2.6.9-rc2-mm2: works as user & root
2.6.9: doesn't work
2.6.9-ac3: doesn't work
2.6.9-ac6: doesn't work
I know I had first successful burned DVDs with 2.6.9-ac3, but I couldn't
get it running agin. The kernel sees the device somehow, but totaly
wrong, corrupted and not usable for burning. As root its often not seen
at all.
Should I try the thing again with the IEEE/Firewire people? This might
be the only solution to this very annoying problem.
