These were published on Region 2 DVD at least in France. I have this box 3-322069-872723. It is still available from Amazon.fr (search in DVD on "Tex Avery") for 50 euro. I didn't check other regions, localities or webshops for better offers, but you might try. There's a bunch on amazon.com too on the same search words, but I didn't check details.
Of course, if you're living in North America, your player needs to be region-free.
