All of the 4k cable provider supplied content will be copyright protected. Sorry.
We are looking for a UHD Digital Video Recorder but have a list of don’ts.
1. Absolutely no monthly service fee
2. No over the air needed, but OTA does not disqualify
3. No satellite tv
We do have cable with Spectrum (I see that they are now the same as Time Warner, Charter, and Bright House if that matters)
The TV is a Sony model XBR-55X850C. It has HDMI inputs.
Three tuners, watch one and record two is sufficient.
The ability to install my own hard drive would be nice, non-essential.
Every where I look the results are cluttered with OTA, direct TV, CCTV, and monthly fees. Suggestions please.
