Audio glitch in DVD Creation

[spaceharfang]

I tried to create a DVD from a mp4(h265/AAC) source into a DVD folder.
The process completed successfully.

Unfortunately, there is an audio glitch (or more, I haven't checked the full result) in the output.

The audio track is an amateur recording of an harmonic orchestra. This accounts for a very wide dynamic range with nearly no audio post processing. So audio clipping is definitely a possibility.
