My housemate and I are trying to share video files that are in our iTunes libraries, but it's not working. I've converted all my videos to .mov format, and we're trying to stream them the same way we do with music. Only thing is, only two of my videos are showing up on his computer and neither of them are playing. I'm on a G3 iMac and he is on a PC. We are both on the same LAN, and song sharing works fine. Whats up with this? Any ideas?
