Home Media Magazine:The so-called "father of DVDs" is involved in a legal wrangle with digital technology company MOD Systems. Warren Lieberfarb, who is credited for pushing the motion picture industry toward the DVD format while president of Warner Home Video, sued MOD Systems last year, claiming the company owes him at least $749,560 in consulting fees. MOD Systems filed a countersuit earlier this month, alleging Lieberfarb overstated his connections to the company, as well as his expertise. MOD Systems recently made headlines for its deal with Warner Brothers and Paramount Digital Entertainment for the rights to distribute motion pictures from the two companies via digital download onto SD cards.
