went to season level - 'c' (context menu) - then choose art.....
from here top right is 'add art' you need to add a new art type discart which isnt available usually in tv shows

you can see here I have already added it
This gives you a new item 'discart' in the tv season section (though haven't played around with it much LOLZ)
Then you have to add manually for each season the disc you want - a slow process if you have a lot of series !!
This gives you a disc for each season ......yay !
I have only made about 15 discs atm - (making work for myself again) but is a different addition not seen elsewhere.
If I can get a good few discs done maybe could speak to the higher powers about including some sort of skin integration....maybe even using artwork downloader if the images end up on fanart.tv - but am a LONG LONG way off just yet
BTW the discs I named them in the tv show folder were the standard as for fanarts and posters seasonxx-disc.png
but as you add each one manually you just have browse to each disc to add it so naming convention isnt really necessary

i see - thx 4 feedback... maybe we can "modify" he artwork downloader like the movieset addon ( with the extrafanart1.jpg )... i will test it next week when i have a bit more time
