ah, I see - that makes sense - thanks

so the best thing for me to do is just parse an existing channels.conf
file to find the frequency and other tuning params for a given service
ID - did anything ever come of the new format for storing DVB config
info and the library for reading it? is there some library that will
parse the existing format and also cope if/when the new format is used?
or should I just assume the existing channels.conf format will be used?
