After playing around with Sky +, I'm now wondering whether to cancel. It's totally useless for recording radio. I want to record my favourite radio programs on a regular basis. Tivo does this with no trouble as it keeps a program database for radio 4. Sky doesn't appear to list any radio programs at all.
Are we living in the bloody dark ages?
Given the choice of Sky 1 and the SF channel or Radio 3 and 4, I'll take the radio any day.
('Listen again' isn't any practical use to me as I can't use my computer in the lounge where I like to listen to the radio)
