Sky Sports 1

My Satellite Setup
Panasonic TU-DSB30 digibox
My Location
West Midlands UK
Sky Sports 1 are showing the WBA v Barnsley game on Sunday 6 May, but it is not the main game and can only be accessed via the RED button. I would like to record the game as I will be actually going to the match. As the RED button is only available after the program starts, is there any way of setting up my digibox beforehand so that it will receive the secondary broadcast? Any help here would be most appreciated.
