For those of you who have not experienced TiVo, it is a similar form of digital video recorder to the Sky+ which currently dominates the UK marketplace. Unlike the Sky+, it has no built-in DVB satellite tuner, and instead connects to your existing Sky box, Freeview box, analogue aerial, VCR etc.
It was and is technically better than the Sky+, supporting predictive recording and over-the-air recording set-up.
Anyway – do a search on ebay UK for TiVo and prepare to be shocked at the prices. Just remember that you will still need to spend £10 a month for the TiVo electronic programme guide subscription (the service still operates in the UK and accepts new signups) in order to get the full benefit of the device.
