I have signed up at the Turn Me Up website, but haven't yet had the chance to watch the video.
The issue of hot mastering and loss of dynamic range has been a concern of mine ever since the 2002 release of Rush's Vapor Trails CD (my all time favorite band).
As released, this CD sounds horrible due to being mastered at way too hot of a level, to the point that a significant amount of the peaks are actually clipped in the digital samples. My disappointment with the sound led me to purchasing Cool Edit (now Adobe Audition) and some other processing tools to try and restore some semblance of decency to the sound.
While not perfect, my efforts allowed me to enjoy listening to the CD without being overly distracted by the poor sound due to the mastering.
Here are some before and after examples of waveforms from the 3rd track, Ghost Rider. Larger images can be found on my photo website:
