I have just bought a 'smart' Samsung telly. Its great, a quantum leap from the last one, a Sony. It is pretty amazing, connected to the internet it can bring back anything. However, there is one function I would like to do but not sure how to set it up. I would like to be able to record, pause, skip etc programmes. As I understand it, I just need to plug in a USB storage device. Is this right? If so, do external USB3 hard-drives just plug in using the standard USB plug? I am a bit naive here.
