Hi Taylor,

I also noticed a crashing backend and I'd set the setup option
"Open DVB Channel on demand"....

After clearing this setting, the backend doesn't segfault anymore :-)

Now I can watching TV and tuning via the number keys without
problems. But if I use the up-down arrows, Myth tunes to weird
channels. I.e. from channel no. 4 to channel 3951... weird.
