This extract from the .nfo is very telling: "For the first time, an edited version of Return of the Ewok is available online exclusively to Hyperspace members. Please note that the picture quality is inherent in the source material -- this is the cleanest version of this rare film known to exist." My emphasis on the 'edited'.
Didn't realise it was a Hyperspace exclusive, but I'd have hoped for the privilege of subscription, members might get more than edited highlights of rare content.
But enough hypocritical whinging, here's a recent article from a Celebration III showing of the film
Mystery Ewok Theater 2005: Return of the Ewok
Makes you pine for a dvd release, with full Warwick Davis commentary. It'd make a perfect extra for any future version of Jedi.
