standard (PAL) signals though often scrambled to prevent people watching the channels without paying a subscription. Cable has not fully transitioned to the digital format (DVB-C) as some parts of the physical cable network are not suitable for transmitting the digital signals. In most analogue cable TV areas, customers received a letter from Virgin Media offering a free switch to their digital TV service. If the customer chose not to migrate to digital, they would've lost all TV channels when the switch off occurred. Customers with the cable feed plugged directly into their TV or have an RF bypass installed, which allows them to watch the analogue terrestrial channels independent of their set-top box, will also cease to receive channels when the analogue signal is switched off. Customers will still be able to receive channels via their digital set-top box. In some parts of the network where digital cable is available, analogue transmissions have been ceased in order that the bandwidth may be used for more data for the digital platform, in others both systems run alongside each other, though often new channels will launch on digital at the expense of channels on the older analogue network, which encourages those users to switch. A TV that is capable of tuning frequencies used for cable is required for watching, plus note that no channels are receivable in Ex-Telewest areas as Virgin Media have stopped their analogue television in these areas. Milton Keynes In Milton Keynes, there has been a cable network ownership dispute between BT and Virgin Media for a decade. Milton Keynes was designated as a new town in 1967 and benefited by having the UK's first ever analogue cable television networks, owned by BT. In the 1990s, EU competition forced BT to sell/lease the service to NTL (later becoming Virgin Media). Since then, BT and Virgin have been unable to reach agreement on physical access, and as a result, Virgin Media are unable to offer digital cable TV in Milton Keynes. In Milton Keynes in 2009, there were about 35 channels available on the analogue cable network, of which 18 were free-to-air. Account holder residents paid at least £4 monthly for TV, which included the following channels: BBC News, British Eurosport, Cartoon Network, CNBC, CNN, Discovery Channel, Discovery Home & Leisure, Universal Channel, Movies 24, MTV, Film4, QVC and Yesterday. There were four optional add-on packs, which include channels:
