Dolby Digital Dropouts with CloneDVD.

Tried to burn with CloneDVD after doing a firmware upgrade to my TDK840G. Defragged HD where Clone is resident and have tried to backup several DVD that have DTS audio. Burn goes well but when I play the result in my standalone, I get audio dropouts. This happens with both +R and -R media. I was using Riteks and CompUSA media when this happened. The problem does not present itself when I burn with Nero6. Is there a problem with the CloneDVD burning engine that hasn't up until now been discussed? I have also updated the CloneDVD software to the latest version..

Thanks in advance !!
