Have created a simple slide show DVD and added background music, all in Vegas Movie Studio HD Platinum 10. After rendering I accepted transfer to DVD Architect Studio 5. On preview in DVDA the audio is fine but after "Make DVD" the DVD has no audio. Tried "Make DVD/ Prepare" and resulting AUDIO_TS folder is empty. Vegas produces .mpg and .ac3 files and these are referenced by DVDA. Any ideas as to why the audio is not recording to DVD, please?
