I'm thinking about cancelling my DSTV subscription and wanting to purchase a new TV that will be compatible to stream online services. I have an old LG Smart TV which is not that smart and doesnt work great. What TV should I be looking to get to do this and are there any additional gadgets that I need to think about too, I'm big on my sports and football abroad so is important for me to have access to these streams. Thanks for help in advance.
