You can record any FTA HD channel unencrypted on the box by doing a manual tune, keeping the Foxsat in non-Freesat mode (channels start from 5001) and rebooting it, then choosing the channel and recording.
You lose scheduled recording this way but you can do what you want with the 1080i streams. I have the 5 FTA HD channels running from 5001-5005 for easy access, and if there’s something I want in HD and I’m able to set the box as I’m in the house it’s really useful.
