moved info from the file format section to the SpotPass page, as that info isn't NVideo specific since all SpotPass content would use it.

File format used for storing videos is not yet known either. Both videos that were available at 18th of July 2011 contained string "boss" in the first four bytes, which leads me to believe this is a [http://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files "magic number"] used to identify this type of file. This header and the crypto used for the payload following it is presumably the [[SpotPass]] content encapsulation format.

This header and the crypto used for the payload following it, is the [[SpotPass]] content container format.(See the SpotPass page for info on the container format) See the above SD storage section for info on the cleartext payload.
The video codec used is unknown.(But going by the manual it should be Mobiclip in some form) Region info is stored in the decrypted SpotPass crypto layer, see above SD section.
