BBC HD changed to BBC2 HD now no EPG data - XMLTV

tscapture doesn't find any of the HD channels

Are you using DVB-T2 for Freeview HD? You might need to choose to scan 'all regions' rather than your local transmitter. The files in tscapture a definitely out of date.

Oops, realised we're not quite talking about the same thing. The 30s comment was in reference to freesat, not freeview. I don't know how similar the huffman stuff is between them but I'd be surprised if they weren't near identical.

I'm pretty sure I read they were identical.

I'm happy to get either a DVB-S Freesat transport stream (from frequency that carries the EPG), or DVB-T2 Freesat transport stream (from frequency that has HD channels), or both.

[imilne]

I can get you a freesat one (once the wee one is finished watching Monsters Inc for the 500th time)...

That'd be good. gEd has provided me with DVB-T files.

Uploading now. I'll PM you once it's available.

For reference (assuming I've understood this properly), the only transponder that can do the 30s trick is TID:2315 (http://en.kingofsat.net/pos-28.2E.php lists two transponders with that ID; it's the one with "Fashion One"), with tuning details (1=11428,H,27500,23). This isn't actually in the Freesat Only.ini file which is an oversight on my part, although I doubt many would care about the single channel it seems to carry.

If I get this style of EPG data loading, then I'm sure I could put some special rule in for Freesat to skip the scanning of other frequencies, and always go straight to this transponder.

Interestingly, scanning on 546000 found more entries

Here is a patch you can try.

For DVB-S, you need to have a channel enabled from that frequency that carries the EPG.

[imilne]

Rather than undo all my existing xmltv mappings, I decided to test by temporarily hiding the xmltv file, and setting up only the following to use the DVB EPG:

BBC One SD - mixed DVB-T/S sources
ITV - DVB-S only
BBC One HD - DVB-S2 only
Fashion One - DVB-S only, on the freesat EPG transponder

I can confirm that all four channels correctly got their 7 days listings.

However, it appeared to scan the DVB-T frequency first, then each of the frequencies for the other 3 channels (they're all on separate transponders). This means it would take ages (~35 minutes) to update the EPG if all the other channels were mapped this way too. I guess it's a tricky one, because you have no way of knowing whether a DVB-S channel is a freesat one or not - and hence whether its EPG could be found on the Fashion One transponder or not - but then all the non-freesat channels (in the UK at least) don't have anything more than now/next details unless you decode the freesat tables.

As an aside, can you also confirm under what circumstances a DVB update will run? Will it only happen if the required tuners are free, ie if Live TV and/or recordings are in progress, then it gets skipped (ignoring the update-during-live-tv option that is usually recommended to be disabled anyway).
