What do you mean by they shouldn't have mulitple adapters numbers ? Multiple WinTV-CI devices should have distinct node parents, ie /dev/dvb/adapter[01]/<node> > > With the transmitted keys changed frequently (at least for viaccess), what's > > the point in supporting offline descrambling when it will not work reliably > > for all ? > > The reliability of offline descrambling depends on the network operators > policy.
