I have the same situation in the UK. Exactly the same TV broadcasts are 
carried on both DVB-T and DVB-S [BBC1, BBC2 etc] The DVB-T multiplexes 
carry full 7 day EPG, but the DVB-S only carry Now and Next. The default 
answer is to use a grabber to populate both, so that with matching 
callsign and channid they are treated and scheduled as equivelents.

However I would preffer to use the EPG from the DVB-T channels to 
populate the same programmes from the DVB-S source. Currently I don't 
think you can use EPG from one dvb source to populate a  different DVB 
source. Is that feature in the pipeline ?
