I share a large number of MP3 files with my daughter, who is using iTunes under Win XP. The problem is that while I can edit all of the ID tags for the MP3 files I have stored locally, she can only edit some of the MP3 files, many of which are the same as mine. They all have been ripped locally from our CD collection, at various times and none purchased online, so there isn't any copyright protection or anything. Is this a known issue? Has anyone else come across this? Cheers, Brian
