I had been using a basic V+ box with HD for about 10 years which I was not really using since I had everything it offered on my Freeview tuner smart TV. Trying to remove the STB from my Virgin package, Virgin offered me the TiVo box for a saving of about £5 per month. The PVR facility has revolutionised my viewing. HD Video quality is fractionally inferior to Freeview though not enough to cause annoyance (SD is slightly better) and the sound (5.1) is slightly fuller through the AVR.
If you are wary about using the latest technology, it is worth looking at the latest thing to be replaced. The catch-up / online services are slow to load up which is my only major gripe. I am a happy bunny!!
