the pc tab is set to on and saved ,but nothing at all comes up on the to pane in the line of disc space.i went into power on set up and pressed reset and also default settings and this has seemes to cure my freezing sd1 problem,i have played 15 mins with no probs .fingers crossed.
it was very embarssing last nite i was backing local irish football stars singing at a charity fund raiser and could not complete a full tune?lucky I was near home and was able to get my x1 over in minutes
