@Mr. V 
I noticed that the load of the Artwortks takes quite a long time.

If they have been loaded before, it is quite fast. But if you switch to a programm where no artwork has been loaded yet, it takes a very long time. Sometimes I have to go back to the main menu and then open Live Tv again until it loads new artwork.  

@Slipass 

Have you put in the api keys in Skin helper meta untils?
That should speed it up a bit.

Besides that it is not instant on my end. about 5 seconds to download and display artwork for one item.
If you scroll to the next item the there will also be that same 5 second wait. This can take a lot of time if you are scrolling though all the channels. 

I experience the same behavior when using skin helper service and it more of an issue the more artwork/infolabels you use.   

@Mr. V 

I have now entered the API key and a central location for the artwork.

When I open the LiveTV menu, the artworks for one or two channels are loaded, then no new ones are loaded.
When I return to the main menu and open LiveTV again, only a few artworks are loaded again.

Do you have the same error?
Unfortunately I can't find anything in the log file.

FYI: This weekend I will test your version 2
