I have in my temporary custody a Several of M4P audio and M4V video files from the days when Apple still slapped DRM on stuff from the iTunes store. They will not play on any computer in either my or Miss von Brandenburg's possession, because the devices are not associated with the e-mail address used to purchase them, said address has been out of use for about a decade, neither of us knows the password and the original purchaser is dead. Ripping them to CD doesn't work either, for the same reason. Any ideas?
