The red button thing is one of those interactive TV things, kind of like a souped up Teletext, but with video. When the main program ends, they continue it "via the red button on your remote" and cover the stuff considered too dull for mainstream broadcasting.
Would be annoying if they did use my photo though, I don't think you can record interactive TV services, so my 2.5 seconds of fame will be lost forever. I doubt they will use the photo though, just had another look on their Flickr pool, and there's damselfly photo's uploaded in the last hour that blow mine clean out of the water. Mine don't even compare to some of them, so unlikely I will get featured.
