A much easier way to see which /input/ (as you really don't care which 
"tuner" is in use and if you know the input you know which capture card 
is in use) is in use is to specify names for the inputs in mythtv-setup 
under Input Connections.  Then, when switching inputs, mythfrontend will 
show you the input name on the OSD (and MythWeb will show you the input 
name on Upcoming Recordings and ...).

You just haven't learned how things work, now.  0.21-fixes is /not/ 
MythTV 0.18.
