Only Thai tv on Satellite is Thai Global Network (TGN) which is a Thai Army run channel, one channel showing a mix of thai tv but mostly public broadcast stuff. It is broadcast from hotbird 13 satellite which may be to low in the sky for you to get a signal up that far north. If you can get it you will need a second dish of at least a 80cm and the alinement needs to be spot on. You can use your freesat box in non freesat mode to tune in to it ( you can toggle between freesat/non freesat in settings on your box) A cable switch can be got to save the changing cable feed to your box from one dish to another. I did the set up a few years ago but its not really worth the hassel for the limited choice you get. My internet is not the fastest in the world, about 2mbps but it just about copes with dootv via the Roku wifi box.
