CloneCD to back up a DVD-A

I’ve learned that Cone DVD2 will not capture\copy the Audio folder on a DVD-A, thou the rest of the backup copy plays fine in the PC and home DVD player. So CloneCD is the true 1:1 copy program. CloneCD backs up all the files on my DVD-A and works fine in the PC but will not play on my standard DVD player. The back up DVD appears to start to load the the player displays “no disc”.
The same back up via ConeDVD2 works but does not have the separate audio files. Has anyone had any success backing up a DVD-A
