I understand that Samsung Timeshift is available but probably not on all later models. I have Samsung UE43TU7100 but no mention of Timeshift. What’s the most lite method to achieve pause live TV, download an App and plug in external hardware storage? Thank you
If your TV doesn't support USB recording then I doubt an app will give you that functionality - you'll probably need a PVR.
FWIW, I actually have both a TV and a PVR that allow you to pause live TV but I never need to because I very rarely watch anything live these days. I either use the PVR to record programs and watch them when I want, or I use the catch-up services after the programs are broadcast. Both of those methods obviously allow pausing when needed.
