Good job!  I ran it on the us and us-tx regions.

On the Knoppmyth R5B7 the heapq.nlargest call gives an error because 
python is version 2.3 and that was added in 2.4.  I replaced the call 
with the definition of heapq.nlargest I found in the python 2.5 source 
code.   I don't know python so I didn't take the time to trace through 
this and see if it was optimal but it did give me "fuzzy" results on 
python 2.3.

I also needed to manually install the python2.3-mysqldb package from 
Debian stable.  I used python2.3-mysqldb_1.2.1c2-1_i386.deb.  Anything 
more recent wanted a libc upgrade.

The -c channel id option didn't work well because I ended up with most 
entries something like "[lyngsat]/xx/whatever.jpg" instead of the actual 
URL.    Three icons did actually have the correct URL.  I didn't bother 
to trouble shoot since the regular mode seemed to work.

I'm still a bit confused about the following options:
"a" to start autospeed
"p" to select preset list entry

Once I made those changes './mythalsig.py -r us,us-tx' gave me the right 
db entries and once I copied the files I had my logos for both local and 
national cable stations.
Much more complete than with mkiconmap.pl.
