MPEG4V requires a large payment to be made to the MPEG-LA group for each unit shipped, which we can not afford to do for the Helix Community. MPG4 audio should work fine. If you need access to the MPEG4-video codec code, you need to sign an additional license from the Helix community and then sign a license with MPEG-LA if you want to distribute the codecs. --greg.
