I have a small problem that has got me tearing my hair out.
if i am copying a self booter copy in 9 out of 10 cases no prob. just some discs come up with application error when using dj3. ive investigated the fault and the image seems not to be a cdi file but a cda file. the question is how do i copy it. there must be a simple solution.
