Are those official release DVDs or independent productions ?
Some of the boxed sets are saying all 9 DVDs, others say all 11 DVDs, others say commercial-free, custom artwork, etc,.
"Video and audio quality are ok. Please note that the video quality will vary from episode to episode. Discs have animated menus.. "
"The series will be on a Dvd + R disc and will come in paper sleeves with no artwork. All dvds are good quality. Multiple movies or episodes are not squashed onto dvd as to save disc space like some other sellers do "
The only official releases I can find are VHS video, and there are online petitions and similar requests for the series to be re-released to DVD. Amazon.com still has a "
Sign up to be notified when this item becomes available" message assigned to the DVD release, although they do carry VHS tapes.
Might be worth a punt.
