Is the content recorded in Vista Media Center protected?
Depends. If you are recording from a CableCARD then everything you record will be protected. Protected content can not be editing using third party programs, burned to DVD Video, or played back on another PC. The protected content can be played back on Media Center Extenders. If you record from a Digital Cable tuner without the CableCARD (unencrypted QAM) then all the content will be unprotected. You will be able to edit it, burn to DVD Video, playback on another PC, etc. Content recorded from ATSC (OTA) HD tuner is not protected. Content recorded from NTSC/analog tuners can be CGMS-A protected. This generally is applied to HBO, Starz, and other premium channels.
