It's a diffusion filter made up of a pattern of microlenses (lenslets). The area on the filter where the image passes through the lenslet is thrown out of focus, whereas the clear areas allow the sharp image to pass through, creating a diffusion effect. This is the basis of most diffusion (nets, Tiffen Soft-FX, Mitchell Diffusion, etc.)

Trouble with Schneider Classic Softs is that the lenslet pattern is regular and the lenslets, which look like tiny bubbles, are fairly large. This is a problem with DV because of the incredibly deep focus; the pattern can come into focus (it can be a problem with any filter with a texture if you stop down too much, like outdoors, so use ND filters). So while you will probably be fine with close-ups shot on a long lens, otherwise, I'd probably avoid Classic Softs for any other shots in DV.

Tiffen Soft-FX has smaller lenslets and a more irregular pattern of them, so this is less of a problem with DV except when you stop down a lot, or go very wide-angle, but then all the diffusion filters start to be a problem at that point.

If you want to stick to Schneider, the Black Frost may be better for you.

In terms of the look, Classic Soft and Soft-FX are less "misty" or foggy while still softening details. They cause minor halation around light sources and don't lower contrast as much. Some small points of light in the background of long lens shots may look like there is a bubble around them, sort of a fuzzy ring, with Classic Softs.
