Macrovision Solutions Corp. has signed a definitive agreement to acquire substantially all of the assets of Muze Inc. The company said it would pay $16.5 million in cash consideration, with the transaction expected to close by the end of April.

By doing this deal, Macrovision is effectively buying the main competitor to its earlier 2007 acquisition of the All Media Guide. Both companies have comprehensive database on music, movies and films, which are used to help power the vast majority of online home entertainment software and digital stores.

Macrovision said it expects the transaction to add approximately $5 million to its 2009 revenue estimates and to be slightly accretive to current 2009 adjusted pro forma earnings per share estimates.

As a result, the company expects that its 2009 revenue will now range between $440 and $480 million and that its 2009 adjusted pro forma earnings per share estimates will continue to range between $1.15 and $1.45.

In 2010, Macrovision expects the transaction to contribute approximately $15 million and $0.10 to 2010 revenue and pro forma earnings.

Muze was founded in 1991 by Paul Zullo and Trev Huxley, who sold a majority interest in the company to Metromedia founder John Kluge and his key executive, Stu Subotnick, in 1992. Huxley left the company early in the this decade and Zullo left right ater Enterprise Partners Venture Capital acquired Muze in 2005 a deal where terms were not disclosed but Billboard estimated to be valued at about $30 million.

The deal was announced after close of trade on April 14 and today Macrovision shares closed at $19.88, up 76 cents on the news.
