Tvheadend

Try increasing the skip initial bytes option in the adapter config.

Have tried a few low values, e.g. 2, 4, 8, 16, whilst monitoring the syslog whilst the EPG scan is running. Let it run for a few minutes on each setting. Problem still there, i.e. Checksum errors still being output and No channels are appearing in the Configuration->Channel/EPG->Channels page.

Does the change take effect immediately after saving the parameters?
What values should be used? The config documentation doesn't give any clues.

When i first setup my ubuntu server i couldnt get epg working.
What worked for me was deselecting all over the air grabbers including eit, and just leaving opentv-sky uk selected, save configuration and boom over 11000 epg entries havnt had problem with it since.

Usually takes a restart of the service to pull in the EPG data for the first time.

Thanks for the info guys. Much appreciated!
I have now configured opentv only as suggested, skip initial bytes set to 8.
Restarted tvhheadend (/etc/init.d/tvheadend stop / start) and now get the following in syslog:

richard@zoostorm:~$ cat /var/log/syslog | grep -i tvh

I get the same result with scan initial bytes set to 16 ( I am guessing these)

I am floundering here, any more ideas, please.

Can anyone help please???

I have tried getting EPG data from XMLTV tv-grab-uk-rt (Radio Times) and am getting the right messages in syslog eg:

but I am not getting any channel data loaded into the EPG.

Is this now a permissions problem ?????
I have made myself a member of hts and video groups and still no channel data loaded.
I even changed permissions on all directories in /home/hts/.hts/tvheadend (they were drwx------ (owner only access)) Used:find -type d -exec chmod 755 {}
Still no data received.

Should I be running tvheadednd as user hts????

HELP!!!!!!! PLEASE!!!!!

HELP!!!!!!! PLEASE!!!!!

Why are you using XMLTV for EPG? Tvheadend is able to use and see epg data from Freeview, Freesat and OpenTV (Sky).

I believe that many of the muxes on Freesat carry the EPG data you may just be missing the home transponders.

I'm more than happy to help you via IRC if you'd like. https://kiwiirc.com/client/chat.freenode.net/?nick=tvhhelp|?#hts (just type /msg mpmc help!) I'm here til 10pm UK time

I have found the solution to the problem! It was me! I hadn't mapped the channels to services as described in Step 6 of the Configuration Guide.
Once the mapping completed, everything started working. I am sorry to have wasted people's time!
As the sign in the Launderette (in 1980's) states: "When all else fails, read the instructions" (I believe this pre-dates "RTFM")
