[vdr] non-root rights

[mailinglists@peess.de]

hi ml,

somebody out there who's also starting vdr-1.1.x as non-root process?

i've got a problem at the switch from driver version 0.9.4 ( non-devfs? )
to 1.0.0pre2 ( only devfs? ).

vdr-1.0.4-aio gets started non-root with media:media standard user
permissions, and does so fine, permissions on devices seem to be no
problem:

0 crw-rw-rw-    1 root     root     250,   3 Apr 15 14:55 frontend0
0 crw-rw-rw-    1 root     root     250,   0 Apr 15 14:55 video0
...

vdr-1.1.27, instead, doesn't find the device if started as this user,
calling 'chown -R media:media /dev/dvb/' after loading the drivers doesn't
work either. if started as root:root, there's no problem at all.
why don't i get at least the list of devices in /dev/dvb/adapter0/ as
standard user ( see down in the logs )?

system is debian-3.0-woody, devfsd starts by default.

as a workaround, is it possible to use the dvb-1.0.0-preX driver without
devfs-support at all?

thanks in advance,
daniel
