First of all, I never suggested, much less stated, that Lucas can be forced to release the original trilogy. In fact, I state in quite plain English that that he "can do what he wants with it," which isn't all that different from your statement that "he can do as he pleases."

Second, from a purely technical standpoint, the original Star Wars has never been released on home video, as the earliest home video versions are from the re-release (with Episode IV in the title)... to say nothing about the alterations made to the sound to adapt to technical advances in home theater systems for the later releases.

Finally, I guess I keep forgetting that not everyone is familiar with the basic rules of netiquette (or perhaps they don't read things in their entirety... too many words, perhaps...? Talk about "arrogance and stupidity"! Anyway, I've digressed...) But while I am certainly curious about the legal ground from a hypothetical standpoint, the "winky" at the end of my post was meant to suggest that my tongue was quite firmly in my cheek.
