I've seen today that 'Sophie Scholl' is to be released on Blu-ray in the UK in October; it will be all-region, and the SD extras will be in NTSC rather than PAL. This has prompted a general question about BDs released in Europe. If a European BD contains extras presented in standard definition, are these usually in PAL? If so, I'm assuming that, even if the BD is not region-locked, my US BD player would not be able to play the extras properly as US players only understand NTSC in standard definition. I fear that the 'Sophie Scholl' release might be an exception in this respect, athough it would be great if I'm wrong!
