Yes I have read the search files and frankly nothing close enough to answer my questions was found. so here it is folks! If I want to save program dmg's or songs or whatever files I would save to a CD to save the expense of a DVD I suppose. what cd? CD-r Cd+r CD-+RW what? does it make much difference? what does the superdrive like? If I am making a music cd for the car I would not use a DVD but a cd I suppose yes? I have no clue if +r -r would make any difference. For backups a DVD would hold more and make more sense I think. Does DVD have +r -r etc caveats? So I Guess I just desire a darn chart telling me when you use what media. anyone see one of those around? Thanks!
