How do you map channel names from DVB-T names to epg source name?

[lchiu7]

I recently installed a DVB-T tuner adapter in gbpvr. gbpvr scans the channels and finds a channel called TV3 (AC-3). I would like to use an xml source for the epg rather than the epg in the DVB-T stream since that is basically only today and next day.

But my epg (coming from an xmltv feed) has that same channel listed as TV 3 in the xml file. The xml file is created via an extract from the epg from a satellite. Short of editing this file before passing it to gbpvr, is there a way in the config application to change the internal channel name to match that in the incoming xml file but also ensure that gbpvr tunes to the right channel when recording?

Also currently when I load up both sources, if the same channel exists with the same name in the xmltv feed as well as in the DVB-T channel list, the DVB-T channel doesn't show up at all in the epg, data or not even though the channel shows up on the config application in the Edit Recording Source option. There is no epg information for the DVB-T source since I have not selected a choice for the epg information. None of the choices (apart from xmltv plugin) are relevant for this source type.

Thanks

It's been a long time since I did this, but essentially you hit "map channels" button, and after the scan you select each channel from the dropdown list box.

ensure the xml with epg data is specified in the capture source and then with the map channels button mentioned above, you can go through all the EPG channels and map them to a digital channel which is found (different names doesn't matter).

if there are channels showing in the EPG which you don't need, you can deselect these.

OK tried this and had some success but also problems.

Found a xml source for the epg for my DVB-T tuner card. Changed the epg source from DVB-S (which I hadn't turned on anyway) to xmltv and pointed to the file. Luckily the same channels which are available on DVB-T and via my cable connection (Hauppauge PVR250) have different channel names.

Updated the epg. In the map digital channels to epg (can't remember the exact wording) was able to map the channel names in the xmltv to the DVB-T channel names (and presumably the tuning of the DVB-T device).

Save it all etc.

Then tried to do a recording by selecting from the epg. Looked like gbpvr started to record but it wasn't writing any data. First saw a file called program_name-yyyymmddhhmm.ts and then about a minute later gbpvr created another file called program_name-yyyymmddhhmm-1.ts.

Both files had zero bytes in them.

Since gbpvr was able to record fine from the DVB-T card using manual recording this seemed a bit strange. Stopped and started the recording service but that didn't change any of this behaviour. Had to delete the recording source, add it back, tune for the DVB-T stations and not define an epg source and the recording process works again.

One thing I haven't tried is to add the epg source, do the mapping and reboot the PC since this could be some strange issue with gbpvr and adding a new epg source to an existing tuner.

But at least I can see how it should work!

One question still outstanding - if the second epg source had the same channel names as the existing capture source, it seems that gbpvr won't define both channels. Short of editing the epg xmltv file prior to loading it, can gbpvr have two channels with the same name but different capture devices.

can gbpvr have two channels with the same name but different capture devices.

Yes. I have four tuners that can record the same channel name. DVB-T, old analogue RF, from a satellite STB and a satelilite tuner.

The only thing is that if the name is the same the channels must be the same. It cannot (AFAIK) differentiate between two different channels having the same name.

I use the same xmltv EPG file for all tuners.

lchiu7, I suspect you may have complicated things for yourself be having mixed an xmltv EPG with DVB EPG in the past. If you'd set you capture sources up from scratch using the same xmltv source, things would have been more straight forward.

Mixed EPG sources often use slightly different names (TV1 vs ONE etc) that make the app think they're different channels.

Actually while I chose DVB EPG as the option, I never actually updated the epg. So while using the DVB-T device, I had no program listings for it. I guess I wasn't sure what to do there. So when I found a decent epg for the DVB-T device tried to use it and hence the question.

Probably not the right thread for this but am having a problem with using xmltv for the DVB-T source.

As noted earlier, every time I add xmltv as the epg for the DVB-T source, that device will no longer record. I do the mapping, make sure the channel is mapped to the right tuner frequency etc. But when I do a record, gbpvr creates a file with the right name but it has zero bytes. Then after about 2 minutes it creates a second file with -1 in the end of the name again with zero bytes. The only way I have found to get the dvb-t source to record properly again is to delete the source, add it back, rescan for channels and reboot the PC.

That doesnt matter - it would have still got the channel names etc from the DVB channels, which is enough to cause this potential problem.

I would have suggested deleting an recreating the source anyway, rather than trying to change the EPG source (since minor channel name variations).

If you still have any recording problems, then reproduce the problem and post the logs and I'll take a look for you.
