Not better files! The files are just the same. Better media or even slower speed (if your burner allows it).
I’ve heard of some people having to burn at 1x speed to replicate certain CD’s. (I hope you won’t have to resort to that)
If you’re wondering what brand of media is best for your burner, look in the user manual. Sometimes they list recommended brands.
And be sure you have the latest firmware and version of the software (update patches etc.) That might sometimes help. A google search turned up
this page for the burner you typed (double check! and don’t update if you bought it much later than the date on the page).
