If possible I'd like to try this. The project that looked smooth but the audio was out of sync.
Can you load that project (make sure the project is using good source videos, not ones that have been re-encoded).
After you load the project goto "Preferences" (F6 Hotkey), assign a new "Working Folder", Ex: (C:\VS11_AudioProblem)
Then make sure the "Project Settings" match your source videos. "File -> Project Properties". If the settings do not match your source videos make the appropriate changes. Then "Save" the Project in the new assigned "Working Folder".
Now goto "Share -> Create Disk -> DVD", this will bring you into the "Burning Module". The Project is carried over from the VS11+ timeline into the burning module.
Click on the "GEAR" Icon and double check the "Project Settings" in the "Burning Module", they should be correct and the same as the timeline "Project Settings" (they should have been carried over into the burning module). If the "Project Settings" in the burning module do not match your source videos then change them to match the source video project. These are the encoder settings that will be used to re-encode the video. Double check them, I would make the encoder use 100% compression as the project settings.
Now create chapters if you want then "Next" and create a Menu.
After you create a menu hit "Close" to save this complete project, in case something goes downhill
Now go back into the burning module: "Share -> Create Disk -> DVD", next, next to the burning screen.
Extra tip: When in the actual 3rd step of the burning module there is a downarrow on the right hand side, clicking on it will display additional burning features.
Click on the "Burn" Icon and let VS11+ reconstruct the project within the burning module. It still uses "SmartRender" as long as the burning modules "Project Settings" equal the source videos settings, but in a different method compared to the "Mpeg Optimizer"
Hopefully the audio will not be out of sync. If it is then I'll post some mpeg editing tips.
I'll be posting the mpeg editing tips anyway.
