So, I take it that now is not a good time to upgrade to the "stable
0.18.2branch" considering I'm also using DVB on a HD3000?
I've been running 0.18.1 for a while and have been waiting until I had the
time to update to the most recent release-0-18-fixes. My main hope was to
fix the problem of mythbackend freezing up whenever it tuned to a channel
with a weak or no signal.
