LiveTV still appears to be broken for standard DVB-t (UK), Mythtv
either hangs or segfaults when I go into live-tv and recordings fail
to start:(.  I've tried following this discussion but it appears to be
about HDTV although the problem seems similar, is DVB still broken?, I
noticed a load of fixes applied to SVN by you last night but these
didn't seem to fix the problem for me :(

I appreciate this isn't much use without stack-traces etc, but I was
hoping it may jog some memories. My log files cheerfully moan that the
channel's PMT is not set fwiw!
