I am not trying to flame or upset anyone in this forum but I think (think!!!) that the reason people would like to see an option to disable autoplay is because there is a chance that you could backup a protected game that would NOT play on a PC if BW or AUTOPLAY was NOT installed.
Ultimately VSO (awesome!!!) will do what they believe is best but they have ASKED registered users to help with the development (bugs & problems) of this software and some people obviously think that an option to turn off AUTOPLAY would be helpful (maybe only for “piece of mind”).
IMHO I would also like to this option but if BW5 can determine if emulation is required according to what hardware you are using and the backup will play on PC without software installed then I believe this should be sufficient!
