I have upgraded to f26 and this driver still fails to tune the "Leadtek Winfast 
DTV2000 DS PLUS TV".

which logs messages suggesting all is well (I get the /dev/dvb/adapter? etc.)
but I get no channels tuned when I run mythfrontend or scandvb.

Is anyone using this combination?
Is this the correct way to use this tuner?


Is this the wrong list? If so then please suggest a more suitable one.


It's the right list. The problem is nobody seems to care.
I have one of these too, I was able to get it tune at one time
but there were some problems that I never ended up running down.

I was planning to dig it out and have a play with it again.

Just to confirm - you're building the media_build git tree on f26


I now installed from media_build with no improvement. These are the boot 
messages:
[included are the two USB tuners: 'Realtek RTL2832U reference design' 
'AVerMedia Twinstar (A825)']

and those drivers are the ones that are not working, yes?


Yes.

If not, you need to try that to get any help here.
Have a look at https://git.linuxtv.org/media_build.git/about/
and let me know if you need further help with that.

It may be possible to get the driver into debug mode and get more
information logged. I'm not sure this will work but give it a go.

First set up the dynamic debug filesystem (may already be there)
# cat >> /etc/fstab
debugfs /sys/kernel/debug debugfs defaults 0 0
^D
# mount -av


Already had debugfs.

Turn on debug printing for the modules of interest
# echo 'module rtl2832 +p' > /sys/kernel/debug/dynamic_debug/control
# echo 'module dvb_usb_rtl28xxu +p' > /sys/kernel/debug/dynamic_debug/control


Have done this. Attached are the messages from a (failed) scandvb that fails 
for all multiplexes.

The messages at the end continued at a high rate after the test finished (until 
I disabled debug
with '-p') and there was no user of the tuners. Maybe IR RC is active?
