You do not need the telephone line if you have cable broadband - you can buy a skype phone that hooks up to your router, so is constantly on, even if your pc is off.
So you can have the broadband and tv for �20.
The V+ service that records programmes is an extra �10 or �15 per month depending on your tv package.
I have a pvr that does everything the V+ does, and it burns to disk as well, which is a big bonus.
As the tv comes through the cable, you can also connect freeview through the aerial - so you can record more programmes, or record and watch different programmes at the same time.
