If you want to record TV, it's better to go for a Freeview Recorder than a TV with USB recording functionalities. Main advantage is that the recorders all come with twin-tuner so you can record on two TV stations at the same time (or watch something on Live TV while you record something else); TVs with USB recording functionalities would only allow you to record a single channel (the only exception to this is the high end Panasonic OLED TVs, which have twin UHF tuners).
