Why can't I use /dev/dvb/adapter0 remotely (using putty) or when not
logged on?

I have a written a script that does scheduled tv recording but it only
works if I am logged on to my FC6 machine at the time the recording
kicks of? I have also found the script doesn't work remotely...the
issue seems to be the associated /dev/dvb device file, I have included
permissions below.

Cheers,

Chris
