There is no direct way to transfer files from a G2 Freesat+ box.
Firstly The 1100S has no way to export it’s recording files.
Secondly to replay non native content a Foxsat-HDR requires sidecar files in addition to the video .ts file.
These can be built using a utility written by Raydon (AV2HDR).
Uploading these requires the installation of the custom firmware to give the required ftp access.
The custom firmware does allow recordings made on a Foxsat-HDR to be viewed on a 1100S either via USB or using your home network direct from the Foxsat-HDR.
If you want to watch Humax recordings made on one box on the other and vice versa easily you need a pair of HDR-FOX-T2’s.
