Burn DVD with CopyToDVD or Plextools?


I burn DVD+R’s from my edited home movies with CopyToDVD and a Plextor PX-760A.

I would like to know if there is an advantage in creating an ISO-file with CopyToDVD first (f.i. for having the layer break calculated) and then burn the ISO-file with Plextools. It is not clear to me if the Plextor Autostrategy Database is used when burning is initiated by CopyToDVD.
