One is an "official" CD called TexLive. Current
version is 6.
This a comprehensive CD, containing lots of information and used
for installation on all platforms. However, even though it
contains eTeX, the right-to-left TeX, it does not contain
all the needed files for typesetting Hebrew.
If you want TeX to run on your MS Windows and you also want
Hebrew within your TeX, it is preferrable to install
from the second CD, the one prepared in the Hebrew University.
