I have original CD which I use to teach Aerobic Classes. Every time I play them on the gym they get some scratch, so I make a copy of original and play copy instead. I keep original for a copyright purpose.
The problem is that on gym's equipment the copied CDs' jump, skip track, stop, in general they do not play the same as original. It is not a problem when I play copied CD's at home or in my car but only when play them very laud in the gym. This is general problem and gym's managers always say that it is going like that with copied CD
Playing original CDs only is not an option because they get so many scratches after a few sessions that they out of use anyway.
At the moment I use CDex under windows to copy Audio CD.
Is there anyway to avoid problems like that or to copy CD with higher precision?
