I'm not sure if this is the place for this, but anyway...
The URL (in the .conf file) for UTV (Ulster Television) should be changed from utvlive.com to u.tv
XML data will now be returned for the channel.
The UTV ID was updated in channel_ids, test.conf, regional_channels and channel_platforms at the end of July to "u.tv".
I'll post a reminder to xmltv-users which is the best place for this information.
