Hi,
Yes, we have had two other similar reports. We are investigating.
What filter settings are you using please? In particular, are you using any or all of the hiss, hum or rumble filters? Also, what version of VinylStudio do you have (see under VinylStudio - About in the VinylStudio menu) and what version of OS X are you running? Could you also please confirm (or deny) that burning the same CD again, without making any other changes, works correctly. Thanks.
