A:AnswerThere is not a DVR function but there really isn't a need as all shows are at your fingertips. As far as the disconnecting Directtv question all you have to do is select which input you want to use with your remote. Pretty easy to use and no disconnecting needed.
A:AnswerYes, you need to have internet service and a wireless router (Wi-Fi) for it to work. However, if your cell phone is able of setting up a personal hotspot, you may be able to use it as your internet connection.
A:AnswerIt connects via wifi and streams content over your internet connection into an HDMI port on your TV. What you get depends on the content provider. Netflix and Hulu are best known paid providers of movies and tv series (old and recent... usually minimum of a few days after broadcast). NFL, MLB also sell subscriptions. Many other providers (religious channels, technical blogs, etc) are free. Some are good and some are junk. If you retain your cable subscription you should be able to stream almost any content provider that is on your cable plan (though that sort of negates the value of the Fire Stick). There are also a few aggregators that provide cable-like bundles of content (Sling TV has ESPN, CNN, Disney, etc.; SkyAngel has Christian/family-oriented content like Hallmark, Disney, etc.)
While the voice search is interesting, the Fire Stick always pushes the Amazon (pay per view) content first and makes you work to find other providers of content. I also have an older Roku box and find its interface more like a cable set-top box. The Roku's non-biased cross-provider search makes it easier to find the free content I want than the Fire Stick, despite the latter's technological advances.
A:AnswerYes Netflix, HULU, Amazon TV have to pay all of them. Guys online will tell you that KODI gets you astound that simply not true. Multiple court rulings in favor of The Big Boys. 99% can be run off a build but if you truly want to cut the cord, you will lose some things.
A:AnswerThe fire stick has been back-ordered because they have a problem with the voice remote for the fire stick from their vendor it wasn't working properly so they wouldn't sell anymore until the problem was fixed and the problem has been fixed as of a week ago and they are now back in the stores the problem is when they come in the store they are sold in one day. The best bet is probably just to buy it online straight from Amazon
