Admittedly late and because this is an old MC version, no-one will care, but that said,
this was the first try to burn using 2 CD's.
First went fine.
MC17 asked to insert a blanc new one, which I did.
MC17 went on spinning, it seemed to have detected the CD. THen nothing happened, except for the spinning circle.
Tried with clicking on 'continue' at what point MC showed a window - what to do, close or continue.
Clicked on continue.
It asked for a new CD which I did, 3rd one.
Same story.
I then clicked on cancel.
MC17 started to burn from the start, the tracks that were already burned.
I stopped, closed.
Maybe the burn software was outdated? So I checked and did a search on 'burn' in the MC20 section. Noticed a lot of issues there, so there is no use to update.
Have burned the 2 CDs but did the split myself.
