I think that you mix things together - it seems that the new mapping table (EPG channel mapping) uncovered things you don't know. The basic XMLTV import behaviour was not changed.

The user is responsible to enable XMLTV sources (modules). If you enable them, they're ALWAYS processed (XML is parsed). The channels from 'EPG channel mapping' come from the XMLTV (as you enabled these sources) - so you see all EPG channels which you can map. But the EPG events are not completely parsed / stored when the TVH channel is not enabled.
And yes - it's better to remove the channels from XMLTV if they're not used to save a little CPU time.

Yes, I keep uncovering things I didn't know about way more often than I'd like to... :-)

Thanks for clarifying! I understand now. Is there some way to see in the EPG Grabber Channels tab, which sources (modules) are associated with enabled channels, then? Apparently the parser "knows" about the connection. I'm thinking of some column, which I could sort by or some filter I could use to avoid manual identification. I have two satellite positions with 558 XMLTV sources...

You should see 'Module' and 'Path' columns. Both of them identifies the XMLTV sources (internal XMLTV import). If you use socket interface (external XMLTV import) - you're bad, because this source cannot be identified - the utilities sends XML to a socket without the TVH knowledge of the source.

Hmh, module is "XMLTV" and path points at "[...]/epggrab/xmltv.sock" for all 558 entries. The ID refers to various microsoft.com sites. Must be internal XMLTV imports from OTA grabbers (EIT and UK Freeview/sat) though, as I'm not using external imports, but no way to distinguish enabled from disabled channels there.

Don't worry. I will wait for 4.2. and do a clean install. Wanted to try the bouquet feature for quite some time now. Will take care of the XLMTV sources then. Please feel free to close this ticket and thanks for your tremendous efforts in further improving and developing this software!

You're using external XMLTV imports through socket. TVH does not know which task pushed data to this socket. If you are sure that no XMLTV "pusher" is running, you may remove all these lines in the EPG Channel Mapping grid. The OTA grabbers are not listed in this grid.

Gee, I must have carried those entries for months and months. I experimented with XMLTV pushers once, but found they woudn't add much value over the OTA grabbers. I have deleted all the orphan entries now and everything is fine.

Thanks again!
