the first number is MythTV's internal chanid

see ChannelUtil::CreateChanID(uint, const QString&)
at 
http://code.mythtv.org/cgit/mythtv/tree/mythtv/libs/libmythtv/channelutil.cpp#n1490

it tries "source id * 1000 + major * 10 + minor"
then "source id * 1000 + channel number"
then "highest channel number of the source +1"
then "highest channel number of all sources +1"

for DVB recorders where the default channel number is the 16 bit
service_id you usually end up with service_id + source_id*1000, like
chanid 12000 for source_id 2 and service_id 10000...
