I discovered that if you use a 'make disk' template with video/audio bitrates set higher than the source MPEG files it doesn't appear to re-encode them (also assuming frame size, frame rate, audio sampling rates etc are the same in the source files and the disk template).
Note the VBR bitrate value in the DVD WS template is equivalent to the 'max' setting in the VV3 encoder - if you do a 'file properties' in DVD Workshop this is the value it reads from the MPEG file (and presumably the value it compares against the template settings to decide if it needs to re-encode it).
