I would assume so. I guess its a size issue with that 242 minutes film. There's a fair amount of demand for it online. Schools could could sure use a completely visualized versio of the play which otherwise only exists in drab BBC editions.
Size isn't an issue anymore... with dual layer authoring now on DVD. I've never heard that Hamlet would ever be available on DVD because of title issues. Which makes my copy of it on LD even more valuable. Same goes with my several copies of the OT of SW on LD I still own.
