In the swedish section, ontv.se is listed. I don't think that site have had any grabable data for years. I think the current site just happens to have the same url as the one that was grabbed.
In multiple sections timefor.tv is referenced. If you open that site in a browser, you get a message that the site has closed. This seems to have happened very recently, as I used it up until last week.
I think that these sites should be removed from the epg channels listing.
