udev issue - the cleanest solution is to write your own rules for DVB
(and other) devices - the following page is a great introduction to
udev and should get you sorted:
Essentially, create the rule for the DVB devices by coping the content
of the existing udev rules file (which could get overwritten if udev
is updated) and create a new rule file (with a filename that is
alphanumerically less than the name of the main rules file) with the
amended owner/group/permissions. These settings will then be applied
everytime the machine starts. I created various groups (e.g.
audio/video/lirc) when configuring my various udev devices and then
add users to these groups when they require access.
