I have two tivo s4s and a mac running pyTivo.
One tivo can transfer files just fine, the new tivo cannot. When I try to transfer recordings from the tivo or the mac, it states that the show has been added to the to do list and will transfer when previous transfers are complete. There are no "previous transfers". I confirm this by looking in the to do list.
I've tried rebooting the box, making multiple calls, and switching between wireless and powerline adapters.
It will stream from the other tivo with no issues, but will not transfer.
The Tivo that works has the newest October update. The other tivo is on the priority list.
