    My other request to Humax is...
    Is there any chance of having HDD settings that allow transfer of TV files a bit faster than 'real time'? Hoping to carry and watch something I recorded the night before involves what I consider to be completely unnecessary usse of USB drives so far. Transfers straight from the HDD of a 9300T were often, quite literally twenty times faster. Wireless is nice but the process seems unnecessarily slow.

    There is two factors here.

    1 The recordings are encrypted on disk, decrypting on copying considerably slows down copying.

    2 Servicing the USB port has a low priority in order to maintain the primary pvr functions.

    You may like to experiment by reducing the cpu load by selecting a radio channel, an off air radio channel or even removing the aerial during copying. These have worked in the past in speeding up usb transfers from pvrs like the Humax 5200T and the Topfield 5800.

    The earlier HDR-FOX-T2 is a lot more flexible especially with the custom firmware on board. To watch content on other kit you can stream directly using DLNA.

    It's time this myth was put to rest.
    There's a simple on/off flag in one of the sidecar files.

    The simple on/off does not actually decrypt the file it merely allows the box to decrypt it during the copying process. Decryption requires a complete rewrite of the data, it's not a on/off switch.

    In any case pretty sure the on/off switch refers to the HDR-FOX-T2. 1800T and 2000T .hmt files. The format of these is well known.

    Afaik no one has been able to access the sidecar files on a 4000T which like Humax 2nd generation Freesat boxes is locked down completely (thought to be LUKS encrypted).

    It's no myth, the CF for the HDR-FOX-T2 (Which is recording the same content) is capable of decrypting content in situ. Decrypted files copy to usb very much faster than ones that remain encrypted. In fact because the bog standard HDR-FOX-T2 will decrypt SD, but not HD on copying to usb, then copying HD is much faster than SD.

    Please would you clarify what aspect is a myth?

    Nonsense. The flag simply says whether or not encryption can be removed (as standard SD recordings can be decrypted and HD cannot). Changing it does nothing to actually remove the encryption.
