Hello all (my first post) !

I've spent quite some time now searching for a way to save wmv files on to the xbox hard drive, unfortunately it appears to be impossible. I've also read that the video files downloaded (trailers and such) from xbox live are 'digitally signed' . Can anyone explain/elaborate on what 'digitally signed' means - i was curious to know if it's possible to somehow 'forge' this signature on to a wmv file of my choice and perhaps work around this issue. any helpful comments greatly appreciated.


thanks
