I once produced an mp3 and included the Author, Contributor, and Copyright fields when producing. The next time I went to produce a video, I noticed once it was produced and played back, that old information was showing up in my Windows Media Player. Now every time I go into the Video Information fields before producing for any new or old project, these fields auto-populate with this once-produced mp3's information. I made a point (and still make a point) to edit the Video Information details to make sure they are blank, and this does nothing to help--EVERY piece of media I produce is stuck with this information. I am able to edit out the Author and Contributor fields for each file's Properties within my Windows browser, but the copyright information is permanently fixed from production. How can I fix this?
