Not finding any of my Tivo Devices (4 of them)

When I click on Discover, it just spins and spins.  I've found all my other devices (Anthem, Sony, Sonos, etc.).  This integration is critical for me because we are still a heavy Tivo family.  Any Suggestions?

I had to manually add my Tivos. 

However, the driver doesn't seem to be sending out the proper commands and a few of us couldn't get it to work.  Please see this thread for more info.  

Dave P is aware of the issue.  Perhaps a few more people with Tivo issues will help give the driver a little more priority.
