Thank you for your response William, last night, and today, I used the link you
sent me and experimented with a lot of different filters and options, but I
have still not managed to successfully download everything..

The initial log-in page address is
<http://courses.cgworkshops.com/login.php?do=logout&u=2518>, and so I captured
that with HTTrack.

This page leads to the main forum page, and so I added that to the list of
filters - <http://courses.cgworkshops.com/>.

Next, there are some separate html pages that I want to download, so the next
link is: <http://workshops.cgsociety.org/workshops/becoming_a_better_artist/>

After that, there are a lot of flash videos (.flv) at yet another location, so
I add another address as well:
<http://courses.cgworkshops.com/extras/becoming_a_better_artist/>.

Finally, I added a filter for several file types.


To close, the final list of filters is:

"-*
+http://courses.cgworkshops.com/*
+http://workshops.cgsociety.org/workshops/becoming_a_better_artist/*
+http://courses.cgworkshops.com/extras/becoming_a_better_artist/*"


Thanks.
