I've a playlist that works perfectly, but I can watch its channels in one device at a time, or rather only one instance of the playlist at a time. I've tried to play two channels simultaneously in the same device, but as soon as one plays the other stops. Obviously the same situation with two or more devices. I've tried to clone MAC Address and also with a proxy, but nothing seems to work. Any suggestion?

Sorry for my bad English; Please, answer by a simple English.
