As I wrote, those channels started transmitting EPG not long ago, so I hope
the issue will be fixed one day. I agree that its probably a provider fault.
Anyway, I think a configuration that will allow disabling EPG from DVB might
be useful for those who retrieve all EPG data from the net, that in most
cases contains more data than transmitted by the provider.
By the way, if we already discussing EPG...
I think the epg.data is very limited. I would like to see an option to
integrate pictures or even movies in that file.
Ofcause I could place tags in description and have a plugin that could parse
those tags and show the pictures stored somewhere else, but I think it
should all be located in the same place.
