Sony is introducing two capacities of its Memory Stick Entertainment Pack for the PSP system later this month featuring either 2GB or 4GB Memory Stick Duo media.

Both versions come with an installer DVD loaded with four movies from Sony Pictures Entertainment, including "Click," "Ghost Rider," "RV" and "Stomp the Yard."

With the installer DVD loaded into a personal computer, one of the movies can be optimized for PSP playback and transferred from the DVD to the Memory Stick media.

In addition, any movie transferred from the bundled DVD to Memory Stick PRO Duo media is also viewable on the Sony PlayStation3 console at 720 x 480 resolution.

The 2GB Memory Stick Entertainment Pack (MSX-M2GSEP3) and the 4GB Memory Stick Entertainment Pack (MSX-M4GSEP3) will be available for about $55 and $90, respectively.

Sony has also unveiled tiny 2GB and 4GB Memory Stick Micro media cards particularly for use with Sony Ericsson and other cellular phones. With the included adaptor, Memory Stick Micro media can also be used with Cyber-shot digital cameras and Handycam camcorders that have a Memory Stick PRO Duo slot.

The 2GB Memory Stick Micro media card, MS-A2GD, is available now for about $55. The 4GB card, MS-A4GD, will be available in November for around $90.
