I would have thought that (re)downloading the listing info in 
mythtv-setup would choke because there is already information for that 
channel...basically only the call-sign, name and xmltvid are changing in 
the channel table....And --refresh-all might be best run only after 
-do-channel-update which is intended to fix (I think) this problem.
