I'm sure this has been answered but I'm finding different answers on the internet. If I stream a show from my Hopper on my home network, is the stream going out to the internet and then back, or does it stay on my local network? I just hooked up a new TV with a Fire TV and the live and DVR streams from my hopper were not great. They were watchable but definitely not HD. If it's staying on my network, it should be high quality with no problems right?
