Some clever sort on the Digital Spy forum has discovered a secret testcard hidden within BBCi on Freeview channel 105. It works on most modern boxes, so to see it for yourself: tune to channel 105 and press yellow when the BBCi background appears. Tune to a different channel, then turn back to 105 and press green when the BBCi background appears. The word “Secret” should appear in the corner. Wait for the status page to appear, then enter 3 3 5 8 2 red green yellow blue using your remote control. In a few seconds, Testcard W will appear!
