Tvheadend

how often do you run the grabber?
how often does your grabber get new epg details?
Did the grabber already run earlier?
How many events where updated then?

Thanks for the attention Rigolo !

I only ran the grabber once yet. It is set to run in every 12 hours.
A lot of channels got mapped but no new events get injected into the database. The epg database stays unchanged (the previously - from dvb source - grabbed epg data)

Maybe the problem is that tvheadend does not overwrite an already existing epg data with xmltv grabbed one.

Did you provide a channel to XMLTV ID mapping on the channels configuration screen?

Yes there are several channels that has an XMLTV source.

I tried the grabber myself but it seems broken.

andoma@norion:~$ tv_grab_huro
using config filename /home/andoma/.xmltv/tv_grab_huro.conf
getting list of channels: could not fetch http://www.port.hu/pls/tv/tv.prog, error: 500 Can't connect to www.port.hu:80 (connect: Connection refused), aborting

How did you configure it?

I do have the same Issue:
I am using TVheadend 2.11 on a Ubuntu 10.04 Server 64 bit and a PVR-350 as Analog Video Input.
XMLTV is configured fine, and produces a file like expected with "tv_grab_ch_search --output FILE"
In the Web-surface some Channels (i do not have a XMLTV source for all Channels) also have a mapped XMLTV Channel.
But it do not Display any EPG Data in The Homescreen:

Aug 18 15:09:59 xmltv: Grabbing "Switzerland (tv.search.ch)" using command "/usr/bin/tv_grab_ch_search"
Aug 18 15:27:38 xmltv: /usr/bin/tv_grab_ch_search: Parsing completed. XML contained 28 channels, 15896 events, 0 new events injected in EPG

Any Ideas? What info can i provide?

Cheers,
stif

PS: Everything but the EPG is functioning impressively well. Thanks for the great work!
