There is no all-in-one solution. I cut the cable a year ago. Cable cutting is so much more than streaming. The Roku (especially Roku 3) is great at what it does, making it easy (sometimes) to locate online streaming content. For me, I was looking for the all-in-one. I wanted to be able to stream, watch live OTA(Over-The-Air, live) broadcasts, and record/watch at will. Roku only streams and much of it's valued content is not free. I quickly tired of the 'insert coin' mentality and have not turned it on in in 6 months. If you have a computer and an internet connection you can get to everything that the Roku offers. If you want to watch and/or record live TV, as I did, then the Roku is unnecessary in the bigger solution. I tried Windows Media Center, Kodi, Media Portal, and a number of other applications, all with the goal of finding a reasonable substitute for the convenience of pay TV and ans a PVR. I found that MythTV running on a linux OS was by far the most powerful and reliable system. Kodi does not have it's own built in PVR recording system. When integrating the MythTV server backend necessary for Kodi to record, I discovered, as lease for me, that the MythTV recording/scheduling interface was better in it's native all-MythTV environment than it was when integrated with Kodi, I was not so interested in all the Kodi streaming capability, so I dumped Kodi all together. It took a couple of months of research, experimentation, and configuration, but I think I'm just about there. Oh yea, about $700 bucks too. Here is what I came up with.
- an Intel NUC running linux Ubuntu 14.04 serving my HTCP(home theater PC).
- an attached USB 1T hard drive
- MythTV freeware installed on the NUC serving as both the backend TVscheduler/recorder, and as the frontend hdmi video input to my TV
- a Channel Master 4228 external antenna mounted on my chimney.
- an HD HomeRUN ATSC 2 channel TV tuner, attaching to both my antenna and my home network. Streams tuned TV channel to any device (incl NUC) on my network.
- a decent internet connection, 15Mb or better.
- a 'Schedules Direct' subscription for all OTA scheduling information on channels in my area of reception. $20 per year.
- Netflix streaming subscription, $9.95 mthly
- logitech K400R wireless keyboard
- TV with HDMI input
With this combination of hardware and software, I can now do it all. If I wan to stream, I simply use the Linux Chrome browser and have created links to all the best sites, incl Netflix, ABC,CBS,NBC, FOX, Couchtuner... The MythTV backend/frontend with 'Schedules Direct' TV schedule lineup makes live TV viewing and recording of scheduled programs easy. I watch at my convenience as in days of old. Ubuntu linux has tools for video/audio screen recording, so if need be, I can record anything that plays over the internet and watch on my TV.
It would be a lie to say that it is a seamless system or that it was easy to get up and running, It certainly was not. Maybe some day son it will be, but for now, I am living proof that it is still possible. Good luck. Your'll get there if you're determined.
