From the website http://www.dielucasdie.com/ you can order the DVD and you get a nice t-shirt if some are still available. There's also a podcast in the site which has the complete film as part of the download. (but this was several years ago) The film is experimental and might seem disjointed, so you might have seen the whole thing. I would guess that clips on online video services are probably cut scenes and miscellaneous, since putting those things out might drive people to the website to buy the DVD.
For me what makes this movie great is that it's one of the first StarWars-ploitation movies. There had been plenty of fan films and parodies but this was the first film i'm aware of that really had an alternative goal but wrapped it up into the Star Wars phenomenom to gain eyeballs.
