If you are truly doing everything correctly and mythfilldatabase only 
downloads 10 of the channels when all are in your lineup, it means that 
the channels have the same stationid in DataDirect (i.e. it's the same 
channel broadcasting on another channel number).

For example, with my DISH network lineup, my local NBC station, WESH 
channel 2, is available as channel 8272 (DISH's 
"unique-within-DISH-network" channel number) and as channel 2 (an alias 
that DISH makes available so I can use the same channel numbers the OTA 
broadcast uses).  My lineup contains 25 channels (12 channels with 
unique and aliased channel numbers and the NASA channel--for a total of 
25).  However, since the unique and aliased channel numbers have the 
same stationid, mythfilldatabase ignores the channel number(s) and just 
populates the database based on the stationid.  So, regardless of how 
many channel numbers can be used for the channel with the same 
stationid, to mythfilldatabase, it's just one channel.

You can look at the raw DataDirect data by installing XMLTV and running 
"tv_grab_na_dd --dd-data datadirect.xml --days 0 > xmltv.xml" (the data 
will be in the datadirect.xml file and the 
XMLTV-processed-to-XMLTV-format data in xmltv.xml).
