Go back by return button or escape key, located in system>setting>add-on and go to this window
[attachmentid=3910069]

install zip file from there

I see, next proceed to video add-on in front, from the long lists look for any channels that belongs to super repo. Or sometime have to look at the program add-on as well.

Have you check and browse into video add-on?

Can you tell us which addons are you looking for? e.g Navi-X, Icefilm, machup etc?

assuming u have installed from zip file, try these steps:

system->settings->addons->get addons
see if "superrepo all" is one of the many inside listed as enabled.
if not, you need to enable it.
then go to videos->addons to check if it is already enabled or not.

but... as i recently pointed out about football today and kissanime (possibly more). the addons appear ready to enable but somehow they don't, can't get them when u click install. this, i am still wondering why. it only happens if u install xbmc new now. i have another one running a not so recent installed xbmc, both kissanime and football today are working, no problem.

i am not sure if yr list of drivingmule, superepo and mash2k3 is missing something...

when i get a problem like that, i tend to install a few more from zip.

trial and error. later can disable those u really duwan. this is one major frustration of xbmc - u dunno or can't remember what is where!

my list has these additional; u can try them and see if u will then find what u r looking for:

xunity talk repo
anarchintosh
bstrsmkr
istream xbmc addons
thehighway xbmc addons

disney... cartoons, animation, anime are usually lumped together. kissanime, anime highway, cartoon world, cartood hd shoud have lots of disney stuff.

i just played around with 12.3 on pc windows.

navi-x is dead - better avoid as u will get stuck.

kissanime, football today working... 720, 1080 good.

dunno why 12.2 on android can't get them... haiz...

It's a PC, full functional normal PC but smaller in size. HTPC basically is mean to play all our multimedia pleasure (not really for work) and SFF is form in size, usually smaller and nicely put beside the TV or any monitor. 

for xbmc, u shoud take a look at this - xbmc android supported devices.

lastly, why android and not htpc, ouya, iso devices? they also can do xbmc...

Toshiba Android TV - has Google Play Store pre-installed.

In fact, more TV manufacturers will switch to Android for their smart TV from this year onwards.

Can't you see the 50" one?
