How does fluxdvd work?

fluxdvd is a technology used by CinemaNow which enables download of DVDs by reducing the DVD size to <2GB.
Does anyone know how this technology works (beyond "the disc is recompressed") or have experience of using it?
they're just doing the exact same thing that the internet video piracy scene has been doing for almost a decade.

Keep in mind, the original DVD is only 3 or 4 gigs anyway. So they're not exactly cutting it down much.

What DVD's are you burning, effugas? Most of my DVD's clock in at 6-7 GB. It's only when they get crammed onto single-layer media that they squeeze them into <4 .7 gb. br>
I only have a couple of bargain DVDs from the "old days" (with no extra features or that crappy, non-anamorphic widescreen that doesn't use all 425 lines) that take up less that 5 GB.4>

To archive the DVD like quality and the original DVD sound, fluxDVD utilizes full resolution H.264 high profile video encoding and original Dolby AC-3 sound.
In simplified terms, they're using the newer (and presumably better) MPEG 4 to compress and ship the video to you. Standard DVDs use MPEG 2 compression. In theory, this allows them to ship video with similar quality but in a much smaller file.
(Of course they're probably transcoding from the MPEG 2 file off of the DVD, not the original uncompressed source, so the quality cannot help but be worse. But perhaps not by much. And if you re-burn the video to a "real" DVD, that's another transcoding step, and another loss of quality.)
