Advertisements I've installed pytivo and love it. However, my devices (computer drives) sometimes disappear from the tivo's device list or it shows a yellow exclamation point. I had tivo desktop and partially uninstalled it as suggested, and then reinstalled pytivo. However, the device listings still show this yellow exclamation. Other share items such as photos and music have no issues, Additionally, I'm able to download shows from the tivo to my computer.
