Comment (by dab at dab-tech.com):
This patch does indeed fix the segfault, but as you say the recording is
invalid. The channels for this source were imported from a channels.conf
produced by a scan from my Avermedia A180 card, which is able to tune
them. I do not get that error message when recording from the same
channel with that card, here is a small excerpt from the mythbackend log
when a recording starts on this channel using the A180 (no cracks about
recording Pokemon, I was just testing ;):

Is there anything else I can provide to try and figure out why I would get
that error message when attempting to record with the hdhomerun and this
source? I'm testing this remotely from work, I will try to see if I can
use the live tv editor on the newly scanned channels from a mythtv-setup
scan I performed using the hdhomerun this evening.
Thanks for looking into this,
Dwayne
