You have to install the TVH client pvr.hts from Settings->System->Addons and set that up with the IP of the device running TVH and the default username and password.
I would have no idea how to update the guide using SSH. It’s stored in the .hts directory of the device you are running TVH on. If you copied that in its entirety, then you should see your recordings after you’ve set up the TVH client.
