Hardware (LiveTV)?

Hi

I just bought a MK808B android TV stick and im NOT happy with the result.
Im not able to watch LiveTV with it.

I have experimentet with serveral different builds, but its not working.
On my phone (Samsung Galaxy 2) LiveTV is workin ok on SD channels.

So now is the question,
What android hardware should I buy if I need to see LiveTV SD & HD?
the hardware should also be able to show HD mkv files.

Best regards
