First off FC4 is fairly leading edge for someone new. I believe I
suggested to the person having DVD problems that they try a less leading
edge distribution.
Discussing and trying to figure out why he was having fits with DVD
recognition led me to curiousity about DVD burners that use USB. I
purchased a Lite-On as lsusb describes below. The permissions for the
device are not set correctly. The owner is root vs. the cdrecorder which
is set to console owner. The ls -la output is below the lsusb output.
What component would a bug lke this be filed against? USB, kernel, the
device manager?
The USB dvdrecorder works fine if I chown the device to jim:jim. I am
about to try jim:disk since the cdrecorder seems to work fine with the
group of disk.
Using the same USB dvdrecorder on another FC4 installation (upgraded
from FC3test to FC3, then to FC4). It did not get things right for an
FC4 installation which is derived from FC4test to FC4 and now
FC4+development.
Other than trying to install FC3 then upgrading to FC4, what should be
looked at to compare differences from FC3 that were hanging around on
the FC4 upgrade that lead to a working system compared to an FC4
installation vs upgrade?
I cannot eject the mounted CD in the condition that it is permissioned
at or burn to the device. I get an ICON on the desktop and the burn
window comes up when a blank CD is inserted. Changing permissions on
/dev/scd0 allows burning and ejection of the drive, as desired and expected.
I still have to create a symlink for /dev/dvd to play DVD's with some
programs. This is another issue though.
Thanks,
Jim
