 A third version of "Dune", seen on KTVU in San Francisco in 1992, is the only  one that edits together footage from both the theatrical and TV versions,  putting back the violent scenes (such as the "heart sucking sequence") and  theatrical versions of some scenes (such as Paul and Jessica running from a  thumper).  Also, Lynchs name is restored at the end (watch for the  "Assistant to Mr. Lynch" credit).
