I'll say this for the folks at New Medium Enterprises: They're nothing if not persistent. The British company has continued to put out press releases and pester reporters for years with tales of imminent developments and breakthroughs for its red-laser based HD VMD disc format despite few of its promises actually being borne out. And yet the company refuses to give up, recently going so far as to hire Michael Solomon, a well-regarded TV industry veteran, as its new chairman to try, once again, to attract interest in the format from U.S. program suppliers.
