I use a box for both mythtv and streaming vlc. I need to kill mythtvbackend to make the dvb adapter available to vlc, which is not a problem. However, something has changed that I am not aware of and even though I killall myth, vlc says the dvb adapter is not available. Is there a way to issue a command that frees up the adapter, regardless of what is using it, or at least find the process that is using it?
