Have found the answer to this, set the AUDIO PROJECT SETTINGS settings in Vegas to  48.Kz and all is well again, no re-render in DVD-A

					Alles anzeigenIf possible, in future, please add the following audio containers: to AC3 audio encoder = (.ac3) container to EAC-3 DD+ audio encoder = (.eac3) container to DTS audio encoder = (.dts) container to ALAC audio encoder = (.m4a) container They will be very useful in cases where only the audio will be rendered. Of all these audio containers, the container (.ac3) is perhaps one of the most needed in video and audio editing. It is one of the most used in DVD, BluRay and video streaming production. IS it possible to have 48Khz sample rate on AC3 as at present it is 44.1Khz and that will not work in Magix /Sony DVD - Architect, it only accepts 48Khz , with no re-rendering before making a DVD 
 Thanks, Makes VP usable for me for DVD and will allow me to move on from Sony Vegas 12
