Tivo Mini - Can't Watch Now - V125 error

For a few weeks now I've been getting v125 errors on my ethernet connected Mini. I've set both my Roamio Pro and its stream address to have static IPs as well as my Mini. Live TV works perfect and rebooting the Mini allows me to watch one single show before the error comes back.

Any suggestions? I'm very tired of rebooting. Changing the network settings works about a quarter of the time. I've rebooted everything multiple times, replaced switches and network cables, repeated guided setup on the Mini (thanks Tivo Support) and done a Clear & Delete everything on the Mini.

Thanks,
Scooby
