If you know the frequencies already, you can find the nearest frequency 
in the table and calculate the difference. I.e., Suppose you have a 
channel at 608000. Now (608000 * 16) / 1000 == 9728. Now, look in the 
table and see if there's a frequency that's close. I.e. Channel 38 at 
607250. Now (607250 * 16) / 1000 == 9716. Finally take 9728 - 9716 == 12.

Now, run mythfilldatabase --manual. When asked for a channel number 
(like xawtv) fill in the channel number (i.e., 38). Then it'll ask for a 
fine tuning value. Fill in 12.
