iTunes content on iPod with 2 computers
I really do not understand what is going on with my iPod. I normally get iTunes store content on my Mac at home. However, today I did not do that and while at work on my PC downloaded a new TV show using iCloud. I then tried to put this TV show on my iPod touch but got the strangest error message. iTunes told me that this iPod was linked to another iTunes library (which it is, my Mac at home) and that if I wanted to transfer this content from my work computer, then I would have to link my iPod to this library. Doing so I am warned will wipe my iPod clean of all the other TV shows.
What is this error message all about? Why can't I transfer a show I bought from Apple onto my iPod using my work computer without wiping my iPod clean? Just exactly what is going on here?
Thank you for your help.
