I am trying to watch a video on my Tivo HD or Roamio Plus that's in my Now Playing list on my PC. Each time I select it, and ask to transfer it to either Tivo it starts to transfer. On the HD I see the blue light turn on. Then it says some message like "Video will transfer when the pending transfer is finished." There is no pending transfer that I can see. I've rebooted the Tivo and stopped and restarted the desktop server. Etc. Any suggestions for what to do?
