DVD's of both seasons can be ordered from this site...
http://www.dvdclassics.webs.com/
I've gotten many hard-to-find DVD sets from this seller and I can personally vouch for both him and his product.
The current price is $20.00 (US) for the 7-DVD set. It contains 36 of the 40 episodes made. Shipping is $3.00 media mail or $5.50 for priority. International rates will vary. He accepts credit/debit cards and money orders. Just email him what you're looking for at this addy: dvdclassics (at) mindspring (dot) com
ENJOY!
