Where can I can find copies of the episodes, on VHS or DVD?
These days, fan (as in, bootleg/illegal) DVDs and VCDs are far more prevalent than VHS, though there are some VHS copies floating around. There are places online that offer copies of the episodes either for money or as part of a trade, as well as frequent eBay auctions…check the links page. FYI, these are all fan creations. The show has not been released officially on DVD. Additionally, there are a few older but official VHS releases. “The Saga Begins” is the one you’ll find most easily; it’s a 90-minute version of episodes 1-5, with edits to the music and the content. I believe this is available in NTSC as well as PAL. There are also a few PAL-only releases in the UK–at least 2 videos, titled “Andorus” and “The Beast and the Bell,” with 2 episodes each. Keep an eye out online or in your local used retailer for them.
