Players, four titles available April 18.

The first HD-DVD titles are slated to go on sale Tuesday (April 18) and, contrary to speculation, Toshiba players have arrived at Best Buy and should be on sale in at least some of the chain's locations.

Sources say players were shipped out beginning Sunday and are scheduled to go on sale at all Best Buy stores and select Sears, Wal-Mart, Costco and Tweeters locations by week's end. Software also will be available at those retailers.

Meanwhile, Universal Studios Home Entertainment is rushing "Serenity" to stores so it will join the two Warner Home Video titles slated to be available for sale today, "The Last Samurai" and "The Phantom of the Opera."

Warner's "Million Dollar Baby" was supposed to be available today as well, but has been postponed.

Other Universal titles in the HD-DVD pipeline include "Apollo 13" and "Doom" on April 25, followed by "Jarhead," "Cinderella Man" and "Assault on Precinct 13" on May 9 and "The Chronicles of Riddick," "The Bourne Supremacy," "Van Helsing" and "U-571" on May 23.

Studios are shipping fewer than 10,000 copies of each title, in accordance with Toshiba's initial shipment of 10,000 players.
