Redesign of sceMpeg: decouple reading of video data for Xuggler and reading of video data from the PSP. This allows an improved compatibility of the PSP video reading without having to take into account of the Xuggler limitations.
This could break the video play in a lot of applications! Please report any regression test issue on the forum.
Changed the naming of the video under the "tmp" directory to support multiple videos having the same file size.
