does anybody know where I can get the episodes at???

I would suggest just looking through bittorrent sites, but that may not be so good as they may only have the stuff put out in recent years. Other than that check out the sites for retail stores, you might get lucky. I saw a few old Scooby Doo meets Batman dvd's at Best Buy the other day.

The original series has been available on DVD in season sets for a while now.

they have them all on dvd
