Atv flash black council

Hi everyone, i want to buy ATV flash black for my APPLE TV 2 jailbroken in fimeware 5.0 (5.1, the last version released yesterday)
But I have some questions…

1/ Atv flash black did support french language (for scrappers, descriptions…etc) YES i’am french, so sorry if my english sucks

2/ Can I play media file like .mkv ? Can i have subtitles with ?

3/ Is it really better than xbmc ?


édit : i have bought ATV flash tv, it’s support FRENCH and mkv, subtitles too
It’s not better in design than xbmc
