I've upgraded to kit Kat before I bought the media link.
I was thinking maybe kit Kat is to blame.
I've tried it with different tv's but no good and I dint know anyone who owns a n HTC phone.
And I tried emailing HTC but they ask for a email receipt number. I am subscribed to then but I still don't know what the reception number is.
I guess I have to return it now.
Did you tried it?
