Audio situation

I backed up a copy of Babylon A.D. with apparently no problems.

Toshiba Satellite X205-S7483
Intel Core 2 Duo Proc T5450
SuperMulti Drive DVD
TDK DVD-R disc

I then played backup copy a noticed a “crackleing” noise with the burned audio. Original disc had no interference.

Any ideas and/or possible fixes.

Thanks

(new to program and forum)

Which copy mode did you use for the backup?
