It's much cheaper to collect the sean patrick flannery movie edits that come with lucas talking at the end of the tapes.
they did not sell very well i'm affraid that there will not be a yound indy dvd release or a blu ray release forthcoming as lucasfilm is mum on the subject.
although lucas shot 100's of hours of documentaries for a future release. Who knows what will happen maybe a future blu ray/hd-dvd release that is interactive under the lucas learning license to be sold to schools to teach history?
