DVDs Play with Very Inconsistent Volume

Thank you for taking a look.
Need to know how to create DVDs that will play all burned segments at the same volume.

Windows 7 64 bit on HP p6710f desktop.

Using Any Video Converter ( AVC ) version 6.3.1.

Copying video from YouTube, converting to NTSC video, and attempting to burn to DVD on DVD-R discs. When produced, the content plays with wild inconsistency.

Some vids play normally. Others are incredibly loud, or incredibly soft.
Many produce a loud strange buzzing sound that I associate with a cheap speaker turned up too loud.

I've tried contacting AVC support, but they are extremely slow to respond.
The files that are malfunctioning are too large to attach to my email, even when zipped.

I tried uninstalling and reinstalling AVC.

I have tried playing the burned DVDs on both a stand alone DVD player and television, and on the DVD player and Windows Media Player 12. Both result in this distortion.

I have tried many different Audio settings both when downloading and when burning, nothing helps. Currently settings under Tools>Audio are Audio Volume>Volume Control: set at 0 db. (trying to change this does nothing to change the audio ).

I have selected Volume Normalize. (whether on or off, this will not work.
AAC parameters: MPEG TYPE: MPEG-2, Object Type: Main, MPD parameters: Encode: CBR, VBR Quality: 4-Middle, MPD Volume: Default, Audio Quality: 0-Best.
Nothing I do will change any of the bad results.


Specific videos that "buzz" and are too loud:
All from YouTube:

The Hidden War over Grocery Shelf
The hidden war over grocery shelf space - YouTube

The 2008 Financial Crisis
The 2008 Financial Crisis: Crash Course Economics #12 - YouTube

This file BLASTS on too loud when played on burned DVD:
Bruce Willis in Moonlighting-Big Man On Mulberry Street-Maddie s Dream(dance-scenes) - YouTube


This next file Tends to be Okay, not great but not buzzy:
History of Ideas Capitalism
HISTORY OF IDEAS - Capitalism - YouTube

I CANNOT ATTACH ZIP FILES to this forum, keep getting "404 File or Directory not found"

This isn't a Win 7 problem but check this out-

You'll likely want to use the "normalize" feature.

If you look at the Original Post again, you will see that I already tried that before posting.
