It's not a guess. The idea is that the waveform BECOMES the original waveform as soon as you apply the filter to it. Not an approximation, not a "smoothed" version of the points, but the real, proper waveform. There is no (read: none, zero, ziltch) advantage in terms of accuracy or whatever else in using a higher sampling rate than you need (which is one that moves the filter out of the audio band).
Please, PLEASE read Dan Lavry's stuff before continuing to ask questions like this; this goes for everyone following this thread. There's no point in us repeating the same concepts over and over.
The arguments behind DVD-A are anyone's guess. Obviously 24-bit is a bonus. Whether or not the high sampling rate is... well, it's hotly debated. On one hand it can make for easier/cheaper filter design in that it doesn't have to be so steep and perfect. They can pretty much start and end it wherever they want. Still, modern oversampling converters make up for this at lower rates anyway, and they're a dime a dozen.
DSD is a whole other argument. It's also one I don't feel qualified to give a proper response to, consider I've neither heard it nor fully read up on the concept behind it. I can relay what I've heard, though: DSD designers have had a heck of a problem dealing with high-frequency noise that the design seems to produce. This could be a bad thing. Others might hear this as adding to the pleasantry of DSD recordings.
I'll leave it at that until I know more about DSD.
