Created movie in Studio Platinum 12 build 896. MediaInfo said they were AVC and audio was AC-3. After creating movie I clicked on Make Movie, chose DVD with Menus, and rendered it. After rendering, it did not open up to DVD Architect as it always has done. I opened DVD Architect loaded movie and  found out I just had abot 75% sound rendered. The first time I set Properties to match Video settings. I tried again using NTSC settings and got same result. I then uninstalled and reinstalled both Studio and Architect, rendered again and got the same results. I will try to insert some images so you will have a better idea. Cannot figure this out. Never had this problem before. I am running Windows 10. Thanks.
