tv has really been frustrating. I've been searching the web for an answer to this, but to no avail. I am only using one iTunes library from one computer with tv. My machine is authorized for two iTunes accounts - mine and my brother's. I kept wondering why some stuff wouldn't show up on tv, and then I realized the distinction. tv is not showing anything purchased with my brother's account. I can play his purchases that I have in my iTunes just fine, but they will not appear on tv. Why????
Similarly, my brother's machine is authorized with my iTunes account. However, my purchases have always shown up on his tv.
