Just had an HD box installed yesterday, connected to a Sony 32S2010 via HDMI. Played around with auto and 1080i, and decided on 1080i output as that seemed to work best. However, I noticed tonight that the Simpsons on Sky One HD had black bars down each side of the screen. The TV was detecting 1080i, even when I changed the output to auto. The same program on Sky One was fine, no black bars, either on 1080i or auto (576p). No other channels do this - even UK Gold works fine on both settings. And the SD program after the Simpsons was fine too. Does this seem normal?
