I recently completed an hour long project utilizing DVD-A 2.0 without much of a hitch. Unfortunately after burning the disk, I discovered a couple of errors in the section containting the closing credits (my fault, not the software) and so I am going to have to fix them in Vegas and go again. I will re-save the corrected DVD-A project under a new file name and then prepare and burn again. I will be using all the same media source files as before with the exception of importing the small clip that has the credits and replace that chapter's source file with the corrected one. Nothing else will change. All of the source files were originally imported from Vegas with video rendered separately using DVD-A template and audio rendered AC-3.
My question is this... When DVD-A recompiles/re-renders the project, will I lose any quality in the process? In other words, will the 2nd DVD burn be of the same quality as the first?
