There's potentially big news in blowing in today, and it comes straight from the Consumer Electronics Show in Las Vegas. Apparently, Sony's been demonstrating the "next level of disc copying" to a curious audience and successfully transferred an entire Blu-ray movie as a lower-res version to a PlayStation Portable's memory stick. More on that at the full story.

Sony has announced its new Memory Stick Entertainment Packs. (We told you about the previous batch here.) These contain either 1GB or 2GB Memory sticks bundled with an installer DVD. This is (obviously) a collaboration between Sony Pictures Home Entertainment and Sony Electronics.

Aside from being able to use the Memory Sticks in devices such as Sony's digital cameras, camcorders and some Sony Ericsson phones, you can also use these to watch movies in your PSP.

The Packs come with installer DVDs for PCs which contain four Sony movies, one of which you can access with the complimentary unlock code, and then transfer to your PSP's Memory Stick media.

The movies included in the Memory Stick Entertainment Pack are "S.W.A.T.," XXX: State of the Union," "The Grudge" and "Hitch."

The 2GB and 1GB Memory Stick Entertainment Packs will become available next month and will cost $100 and $60 respectively.
