[mythtv-users] Clunky tuner detection in mythtvsetup

[John Pilkington]

I have two devices with three DVB-T tuners on this box, running 30pre3 
with the 4.4.79-1.el7.elrepo.x86_64 kernel.

$ dmesg | grep adapt
[   18.492232] DVB: registering new adapter (Kworld UB499-2T T09)
[   18.497274] usb 1-1: DVB: registering adapter 1 frontend 0 (Afatech 
AF9033 (DVB-T))...
[   18.500472] DVB: registering new adapter (Kworld UB499-2T T09)
[   18.516789] usb 1-1: DVB: registering adapter 2 frontend 0 (Afatech 
AF9033 (DVB-T))...
[   20.417032] DVB: registering new adapter (saa7133[0])
[   20.417041] saa7134 0000:07:04.0: DVB: registering adapter 0 frontend 
0 (Philips TDA10046H DVB-T)...

The adapter error rates vary, 0 being the best and 2 the worst.  I aim 
to have multirec settings of 8, 5, 5.  I have had this in the past but 
recent trials had upset things;  yesterday I saw a gap in the schedule 
and tried to improve matters.  It was a frustrating experience and I'm 
not yet sure that I got what I wanted: a simple and logical assignment 
of 'virtual tuner' numbers.

The card identification process showed the type but probing often failed 
to show the device identifier, and restarts always involved lengthy 
searches for disecq trees and upnp devices like VBox, which I know I 
don't have.  The kernel identified my hardware soon after boot.

There was some work on this sort of thing at Ticket #12547 but setup is 
typically done once and then forgotten.  Have I missed some shortcuts?
