Greg can't mirror his phone with his Samsung smarTV, but he can use his hub to search the internet. Leo says the TV has to be cast-enabled to do it, and the feature may not be turned on in the settings. It could be DNLA or AirPlay. But it also says "smart hub is trying to update." Leo says that Samsung is notorious for not updating their TVs, and it will eventually get to the point where it can't be updated online. It's clearly looking for the update though. Samsung does suggest you can reset the country and that will fix it. The wrong country code could very well cause this issue.
Dennis is an audiophile and he's having issues playing music from smartphone using Google Chromecast. It wants him to upload all his music to the cloud first. Leo says that his casting app may be corrupted. He should try another one, like AllCast. From the chatroom - Google requires you to upload your music to the cloud before casting with Google Play. That's what it's designed for: to play from the phone at home using the Google Home App.
John is having trouble chrome casting with an app called Hoopla. Leo says that it's likely a rights issue, and Hoopla is preventing it on the Chromecast, but works with the iPad. Hoopla has apps for Roku and Apple TV, and they work more consistently. Leo's guessing it's a problem with Hoopla and poor Chromecast implementation.
Adam has stopped using Chrome in favor of Firefox because it's gotten a lot faster. How can he cast from his browser like he can from Chrome? Leo says that Chrome does it natively. Leo says he'll need an extension from Firefox to do it and that may be hard to do.
Jerry has a laptop and he wants to know if he can connect his Apple TV to it so he can watch movies. Scott says that if the laptop is a Mac, then AirPlay with the AppleTV will make it easy. If it's a Windows laptop, then Miracast is what Windows supports. Both the laptop and TV have to support it, though.
