RealNetworks CEO Rob Glaser is remaining confident that people will be permitted to use the company’s RealDVD software to copy DVDs to their computers. Glaser said he believes the digital entertainment company will win a legal suit filed against it in October by 6 Hollywood studios. He also confessed that if the company is required to make small alterations to its software  it will be done.

The studios contended that the software permits video pirating. The program was introduced in late September and allow consumers copy DVDs that could subsequently be played on up to five computers per user. The studios that sued RealNetworks are Viacom Inc.’s Paramount Pictures, Sony Corp.’s Sony Pictures, News Corp.’s Twentieth Century Fox, General Electric Co.’s Universal, The Walt Disney Co.’s Disney studio and Time Warner Inc.’s Warner Bros.

RealNetworks has said the software does not remove or change the “content scrambling system,” or CSS, encryption that is part of commercial DVDs. RealNetworks is subject to a temporary prohibition on the distribution of the software, placed by a federal judge in San Francisco.
