I have installed vdr on my father's Kubuntu 14.04 Trusty machine so I can record TV remotely while he is not there. It seems to meet my needs (not sure about autoboot and shutdown yet) but it disables kaffeine, which he uses to watch live TV and occasionally record.
It appears that vdr locks the tuner /dev/dvb/frontend0 even when it is not recording, so kaffeine cannot use it.
Is there some way I can get kaffeine to proxy through vdr, or get vdr to release the tuner when it is not recording?
