Here's the short version of this question, first: I have imported HD video into a Premiere Elements 11 project running about 90 minutes. I have removed various clips from the video to cut it down to about 60 minutes, and then rendered the remaining video as a Blu-Ray disc. The video looks flawless. But for each of the 11 video clips, the audio plays at full volume for about 8 to 10 seconds, and then gets dramatically quieter. Background noises, though, remain fairly at the same volume. I have tried various tools within PE11 - including fidgeting with Audio Gain, the Audio Mixer, and keyframes, without success, so I'm hoping someone here will know the answer.
Now for the details as recommended by the forum's administrator:

This started with one large HD MPEG-2 video file, 9.63 GB, running 94 minutes in length (1:34'12"). HD resolution is 1920x1080 (full HD). Video data rate is 15,454 kB/s, total bit rate is 15,838 kB/s. Frame rate, according to Windows' file manager, is 29 fps. Audio bit rate is 384 kB/s over 6 channels with an audio sample rate of 48 hHz.
This single file was split into 11 clips, each having the same basic characteristics as the original (length of each clip is the only difference).
There are no other assets in this project (no titles, no other layers or tracks above/below). It is just this single video clip.
3. The Project
The project was created in Expert mode, using the time line, the time bar controller (the turquoise slider control), the scope marker (which indicates how much of the project is visible at any one time), and the Scissor tool (to remove unwanted video footage).
The duration of the timeline is 94 minutes, and there are 11 clips of varying lengths end to end.
The process for creating this project was as follows:
a) Import the single asset (as described in section 2 above).
b) Use the Scissor tool to remove 10 sections of video from the original file, leaving 11 separate clips.
c) Create the main and chapters menus using the Menu Maker. (Two 1920x1080 static bitmaps were imported to customize the layout, and I changed several fonts as well.)
d) Render the final video to DVD and/or Blu-Ray.
Upon seeing there was the issue with the sound fading approximately 10 seconds into each clip, I tried the following:
e) Adjusting the Audio Gain on each and every one of the 11 clips, re-rendering and reburning the disc. Results were the same.
f) Adjusting the Audio Mixer for the entire project, re-rendering and reburning the disc. Results were the same.
g) Adding a keyframe to the first clip, and dragging the yellow volume line higher after that inserted keyframe, then re-rendering and reburning. Results were the same.
I'm hoping there is some feature or adjustment tool I'm overlooking but I have scoured the entire software (I myself am a software developer and know about testing software) but did not find anything suggesting what may remedy this issue. Has anyone else experienced this? What other options do I have regarding such audio problems?
