No, because the HDHR and other digital tuners have *no concept* of
what the virtual/box channel number is-- it doesn't have the
information you want it to put there! This is why most people simply
edit the channels and put the xmltvid's in-- then you can run
mythfilldatabase --do-channel-updates and it will fix the visible
values to be what you expect. You are trying to do it the opposite
way of how most people try, by getting mythfilldatabase to match
channel number instead of simply telling it which xmltvid applies to
Regarding your SQL. yes, assuming you haven't changed any channel
numbers, that would clone them into the freqid table.
