Does anyone know why some items (music/movies/tv shows) I bought over the years show up as purchased when looking on the iTunes store front but others don't. It seems completely random, especially as somethings show up as purchased on my iPhone but not in iTunes. Others don't show up on either but I have no problem re-down loading them if I delete them. Any ideas? Sorry if this has been discussed elsewhere - i tried searching the forum but could't find anything relevant.
