Dave has a mobile phone and he wants to know how he can stream to his TV from it. Leo says to get the Google Chromecast. This will allow him to pull up a video stream on his phone, and then hand it off to the Chromecast to put it on the TV. He'll need internet and Wi-Fi to make it work. If all his internet access is through his phone, then he could use a hotspot with his TV if it supports that, and then Chromecast that way. But he'll take a bandwidth hit on his phone.
