HALion Symphonic Demo VS Boxed retail

Is there any difference in the supplied demo dvd for Cubase 7.5 and the full version? How could you manage to get 27GB into one DVD, when the retail version contains 3 DVD?
I bought Cubase 7,5 and installed the HSO demo, bought a licence and like it alot, but im just wondering if there is a difference. The price at Amazon is much higher than the price i paid for a licence to the demo, $130 compared to $625.

There are two flavors, the VST Instrument Set which you have (and I too) has only 16 bit samples. The item you linked to has 24 bit samples as well.

Ok thanks!
