works here make sure you use wg++ 5.5, update siteini.pack, you should have mytelly.co.uk.ini -- Revision 02 also check channel line
<channel update="i" site="mytelly.co.uk" site_id="1229/sky-sports-main-event-hd" xmltv_id="Sky Sports Main Event HD">Sky Sports Main Event HD</channel>
mytelly.co.uk.ini -- Revision 02
On rev 2.0 now. EPG grab is inconsistent — sometimes OK, sometimes fails, even for the same channel.
Suggest you use the setup here: https://github.com/SilentButeo2/webgrabplus-siteinipack/blob/master/site...
you can either copy content or rename file and add license/channels data.
The site is blocking grabbing too fast. They have added a captcha So i think is the case to add of delay in show detail, will set it in the site.ini, so re-download siteini
It's probably better to use other sources.
