I have a Android media player etc
I have the Android media player, Roku, and a 4k smart TV. I also have triple play cable.
Most of the Android apps are free like Plex, the Roku supports pay and free apps including ones tied to cable movie channels, and of course cable charges but I get TV, net, and phone for my money. For just about any alternative you still need Internet access so unless you get free wifi you still need to pay for internet service to run any of them.
The plex app on Roku is free, easy to use, and works well. My Android box plays anything on my pc network video or audio files and does a great job with plex and has browsers and all kinds of Android apps. The TV does YouTube 4k, Netflix 4k and other easy to use apps built in.
Cable is cable and they recently added Netflix too plus their on demand free and pay extra stuff. I also bought a HD HomeRun Prime that has 3 cable tuners as my cable DVR. I can copy, edit, move just about any hd video I record with it and can save to any drive on my pc.
There are lots of free or cheap choices so do your research before you get something and realize you need something else to actually use it. Almost any solution still requires a internet connection so pretty hard to completely cut the cable.
