I have been using it a couple of weeks now to 'solve a problem' . I have 400Gb of content on the Freeview box which has not been played yet. I want to watch some of the recordings in my holiday flat and don't want to keep dragging a second Hummy box too and fro in hand luggage. I discovered early on that the Hummy file format on the FOX-T2 drive is scrambled (unlike the Foxsat) . My solution is to archive the content (slowly as a background task) to virtual drive space on the internal 1Tb drive. Then using an external SATA loop I added through the Hummy conditional access slot, I port the virtual drive content to an external 1Tb USB/SATA SATA drive in a caddy using the pc and the Ext2 Linux file utilities (those are great!). Then I play that through a cheap O!Play HDP-R1 media player (which reads EXT3!) to my second HDMI TV. To update content I only need to carry the portable drive. I guess this is what most are doing, but I am just starting with a lot more to learn!
My only problem is my wife now complains about the 4 icons that come up on the screen everytime she starts up the hummy. Not looked in the browser menu yet to see if that can be stopped.
Great firmware mod!
