Beware! I got bitten thus

I built drivers, needing the kernel stuff, time passed but I had to go back to update \
a driver that worked with kernel n-2 but not n (v4l API is all over the place) \
Eventually I licked wounds, defeated! Tumbleweed goes not provide previous releases.

Could that relate to mythtv. Like so ..
On tumbleweed n- mythweb worked
On version n it stopped working (python)
Go back to version n-. Yay I've got the iso. Unfortuantely zypper won't play.
No mythweb !!

If you need/want a rolling distro arch looks better (but I've not played enough yet)
manjaro or endeverOS may give you a gentler install experience.

The mythtv devs seem to like ubuntu, which I dislike, if you use SuSE then say no \
more. But ubuntu experience is works-well, specially if you build packages.
