I am trying to create WMA files to put into my Media Centre which uses Media player v 10 to play them. If I update the Band field on MP3 files all is well but if I try it with WMA files then the Band appears in MP3tag but not in Media player's Album Artist tag after loading. All the other tag info is correct in Media Player. If I update the Band/Album Artist in Media player then MP3 Tag is happy to read them as is Media player. I know media centre has a habit of remembering old tags for some reason but these are new files and I've also tried deleting Media Centres tag libraries to force it to start again.Am I missing something?
