I know this issue has been discussed before but I still have some questions. Background. I receive some channels from more than one source and one of those sources carry a couple of days of EPG but suffers from low signal quality so I'd rather not use that source when recording/viewing. So I was thinking of exporting the EPG from that source and import it to my other sources EPG-data but found out that the <event id> and <table id> differs between these sources. What sets the <event id> and <table id> and are those values calculable? If these values are not calculable I'd like to know if there is an counter part to <table id>=0, that is - always overwrite this event if conflicting data comes from the DVB stream (conflicting as in overlapping start time and duration).
