What any screen reader user needs to understand is that issues of inaccessibility can originate with the screen reader itself, the software you're trying to use it to control, or both.
Your request is not unreasonable, but be aware that it may have nothing to do with NVDA (or any other screen reader) and may have everything to do with something the folks at CyberLink have done (or not done) with PowerDVD Ultra 19.
There are times, of course, where both sides of the equation will have tweaks that must be made.
