I have all of my music and videos on one Windows PC in iTunes 7. The videos are mostly TV shows that I've converted from MPG with Videora. I have that system set to share the entire library. I have another Windows PC on the network, also with iTunes 7. I get the playlists from the first PC and I can play all of the music from the second PC. When I try to hit Play on a video, though, nothing happens. The Play button depresses for a couple of seconds as if it's trying something, but then it pops back up and nothing happens. Is this not possible in iTunes? Does it have to do with the conversion method?
