Virgin media cable - Red button on BBC channel works... But actually just takes you to channel 991 (RB 1) or 992 (RB 2).Digital cable (UK only): pressing the red button on a BBC channel? (I don’t have cable, so I’m not sure)
Quicker and easier to go directly to 991 / 992 than use the BBC interactive red button, and futhermore you can schedule recordings on these channels.
They're not HD though, so BBC2 wins if it shows any skating (and they have been showing some of the skating live... duplicating red button... but in HD).
