You can try MP3 Producer (shareware, not free) from this link http://www.mp3developments.com/mp3producer.php or elsewhere.

Failing that, you can ask someone to create a simple Visual Basic or elementary C++ program that can either handle batch operations parameters (e.g. my*.mp3) itself or can be used in batch mode with a single file parameter, to find and set/reset the Copyright bit in ID3 tag info, possibly using this structure and calls - http://docjar.com/docs/api/joeshmoe/mpeg/MPEGInfo.html.

Hope it helps.

Thanks for the help. I downloaded MP3 Producer and gave it a look. Like the others, it does not address the copyright bit. I will have to keep searching.
