You may need to go over to the channels editor tab, find the entry for the newly mapped channel and type in a name for it there.

Sorry, thanks but I don't understand that and I'm confused. I just went to /Configuration/Channel / EPG/Channels and Sky Arts is listed there and all details seem to be correct AFAICT. But the channel name doesn't appear on the Services page as I said, and nothing appears in the EPG. What do you mean by 'newly mapped channel'?

Hmm, curiouser and curiouser. I just went back to my TVH browser tab. Now on the TVH services tab I see that Sky Arts has a 'channel name' displayed of a0b72451c6bdf7f90f7c0e7ec8afcd1b and some Sky Arts programs are appearing in the EPG. But the channel name still does not appear in the EPG filter channel list (neither Sky Arts nor a0b72451c6bdf7f90f7c0e7ec8afcd1b) and the Channels tab still looks the same as it did before.

What on earth is going on?

Did you fill out a name here:

"Did you fill out a name here:"

That isn't possible. Double-clicking on that field makes a list of choices pop up. The list doesn't include Sky Arts as I said and it isn't possible to type a name in.

This is done via a menu entry. Sorry for the German screenshot, but it should be something like "map selected services/map all services"...

Yes, as I said I tried that initially. It didn't succeed and there's nowhere to type in a name manually. Thanks for trying to help.

If it didn't map at all is it a blank service? On Config/Dvb/Services tab on each service line there is play button and then info button. Click on info button. Does it show PIDs for video and audio like so....

After filtering and reordering (without PCR and PMT)
Index PID Type Language Details
1 0x0065 / 101 H264
2 0x0066 / 102 MPEG2AUDIO
3 0x0067 / 103 MPEG2AUDIO

Or blank like so....

None

Channel names can be entered manually at Config/Channel/Channels. Double click on name, type in name, click outside box to exit typing and then save. Search on Services column to find right one to edit.

It was blank as I said. Now it shows as a UUID-like name as I said.

The info button shows:

Sky Arts has always appeared in the Channel/Channels tab list as I said, so there's no point in trying to enter it I think. The question is why it doesn't appear in the list of available names on the Services tab.

Not quite sure. Service tab should show service name that was read from SDT in transport stream. When you map service it should create a channel with the same name as service name. Sometimes SDT not setup right by broadcaster and service name is blank. In that case when mapped a channel is created with name like network/mux/PMT# in TVH4.3. Can't remember what it did in 4.2. In that case you go to channels tab and edit name to what you want. Channel names in services tab are only what you have on channels tab. If the channel is named like UUID in channels editor that is what will show up in drop down list on services tab.

Can't say what went wrong when mapping service.

Thanks for the information. It seems to me that TVH is conflicted.

'Sky Arts' appears in the list of channels on the Channels tab.
It does NOT appear in the list of channels in the filter drop-down on the EPG tab.
It does NOT appear in the list of channels available to select on the Services tab. Instead there is the UID-like channel name, which does NOT appear on the Channels tab.

Where does TVH store all this information? I'd like to look at the actual data files to see if I can figure out what's going on.

At the moment I can record Sky Arts programmes but I can't find them by channel, which makes selecting them problematic.

In the ~/.hts directory of which ever user the TVH server is run under. Generally by default /home/hts/.hts

I would probably suggest deleting any channels for Sky Arts and the MUX for Sky Arts then recreate the mux, scan and map services to see if that sorts things out before poking around in the config directory.
