I upgraded to Premium over a month ago and I did not write down which were the original soundpools. But, these I do know for sure:
Ambient Vol. 7
Chillout Vol. 3
Disco House Vol. 9
HipHop Vol. 10
Rock Alternative Vol.1
While it is not a bad selection, many of the instrument groups were pretty thin or contained no content what-so-ever! If you want a decent library of content, you are pretty much forced to upgrade to Premium.

I just took a look at the Basic DVD and I did miss one soundpool. You can add this to the list:
Techno Trance Vol.11
These are the soundpools added with the Preminum upgrade:
Flamenco Rhumba Vol. 1
Latin Vol. 3 100 BPM
Minimal Electro Vol. 7
Movie Score Vol. 6
RnB Soul Vol.2
