I've 3 TV cards that find the same tv channels. In the Guide I see 3 time the same channel: How can I avoid that? How can I see only one channel per name?
Its normal to enter the epg info separately for each source. If you're using the xmltv source, and the names are the same for each capture source, then they should end up being the same channel, and only listed once in the tv guide.
If you'd chosen the EPG source 'none' and manually added the channels, then they're always treated as unique channels, regardless of whether the names match channels manually added in other capture sources.
the first board is XMLTV, the 2nd and 3rd are none. I added manually MTV on the 2 and 3 and it appear 3 times. Now I use EPG DVB for the 3rd but nothiing changed.
