TVonics MFR-300 review

Reviews There is a very specific problem on the horizon: the analogue switch-off. Instead, it features RF modulation, which means you simply tune your TV's existing analogue tuner into a special channel the box broadcasts.

HDTV basics

Reviews Analogue: An analogue TV cannot display progressive-scan DVD or HDTV. The biggest problem is that 20-25% of the population will not be able to receive Freeview unless the analogue switch-off gets underway.
