I have a PC and a Windows Phone 7. I have downloaded several .mp4 TED talks. I put them in the "My Videos" folder, but Zune isn't adding them to my collection. Thus, I can't figure out how to sync them with my phone.
How can I force them to be added to the collection, or manually sync to the phone? Is it possible that they have been added to the collection, but just aren't visible?
