This are 2 things:
First: The wrong schedule.
Indeed these service refs are linked to the wrong EPG. This happens when somebody gives me the service ref and say it is ITV1.
I do not live in the UK, so I cannot check.
Corrected these.
Secondly: No descriptions
There are descriptions in the XMLTV file.

If you do not have them on your receiver, a reason could be you are not importing them.
In the config screen of the EPGimport plug-in, set the import of description for 7 days (or any value you want).
Setting this to 0 will skip the import of the descriptions.
