Hi,
I've just been doing something similar for my parents, they are now able to watch most Spanish television Tve1, and quite a few others although I can't seem to load playstore apps as they're incompatible.
But the channels they're using are in:
XMBC>World tv> Live TV (I don't recall if I found and loaded this or if was already there as standard)
Until today you could now scroll down very easily in a list, but now you have to go down 20 odd pages full of TV logo's until you get to Spain, the pages are listed by country... Just race down until you see alot of South Korean flags then slow down... Spanish TV is there...
There are also many Channels under XMBC>World Tv> World TV
