The day before yesterday I downloaded an iTunes TV show on my iPad while I was on vacation.
This morning, I was playing with my iPad after turning on iTunes on my PC. When I looked at my iTunes library on my PC, I noticed the tv show I had downloaded on my iPad had been added! The "date added" field of the file on iTunes shows that it was added this morning. Importantly, I had not yet synced my iPad and my iTunes!
Does anyone know how this happened? I do not know how I accomplished this or how I can replicate it. But it's awesome! Could this be related to my Remote app or some Home Sharing feature I inadvertently activated?
