Can existing HD recordings be decrypted?

I've tried searching for an answer to the question in the title but all the results appear to be several years old, or for another Humax model.

The long story short is that I have some old HD recordings that I would like to preserve, and I want to understand what my options are.

1. Can existing HD recordings be decrypted?
2. Is it possible to get the encrypted recordings to play on another Humax device or are they tied to the specific unit*?
3. Could I use a HDMI capture device to capture the encrypted recordings?

*It's my understanding that the Foxsat has a built-in chip, that is responsible for the encryption. Therefore the recordings need that specific chip (or more to the point, the unique key it contains) in order to be decrypted.

Nothing has changed. We know how to decrypt HDR-FOX and HD-FOX, we do not know how to decrypt anything else. Encrypted recordings are only playable on the actual machine that originally recorded them, and in some cases it is possible to trick it into exporting a decrypted copy.

I already have a Matrox MXO2 Rack MAX, which can capture via HDMI... So am I right in saying that the main issue would be the HDCP?

There's only one way to find out...

Not strictly true. Not really relevant to this Freesat thread but the "Foxy" trick (patching the .hmt file to trick the Humax into allowing copy with decryption of HiDef) that works for the Freeview HD/HDR-Foxes also works for the 1800T/2000T. As for the 5000T, even I wouldn't want to use the method that exists to copy/decrypt HiDef on this - and I posted how to do it! See here

Did I not cover that in my previous reply?:

Does Nowsters patch still work to bypass the recordings being encrypted in the first place? It certainly doesn't work on existing encrypted recordings.

@MartinLiddle Nowster’s patch does not decrypt existing HD recordings before the patch is installed.

Martin already knows that. So that is why he phrased his post as he did.
If anyone missed that detail in the first sentence of Martin's reply it is also there imbedded in his second sentence as well.

It is good that you agree with what Martin said and emphasised.

For question 3, I say yes. I've done it by playing the programme into my laptop via an HDMI to USB converter, while recording the full screen by OBS Studio. I then edited the file with VSDC free video editor, and copied the result back into the Humax via an HDMI cable. However there was loss of quality because HD was converted to SD, and probably the frame dimensions suited the laptop rather than the TV.

Asymmetric Digital Subscriber Line? I don't think so! You can only mean via the Ethernet connection, which implies some kind of network file transfer.

If you say so. ADSL seems to be used interchangeably with Ethernet according for cables online. My laptop calls the square jack a RJ45 (network) jack.

No it doesn't. Get a clue (you would seem to need several actually).
RJ11 is used for phone/xDSL stuff. RJ45 is for ethernet networking. Clearly they are not the same thing.

It's not square. It's rectangular. The RJ11 is more square than the RJ45.
Can you actually write anything that is not wrong?

The connectors are similar in style but not the same, and use different specifications of cable. They might be listed in the same sales page, but you can't use them for the same thing. For one thing, the ADSL cable from your master phone socket to your modem/router has only two wires and uses a 6-pin plug, whereas an Ethernet cable has 8 wires and an 8-pin plug (although only four of them are used for anything less than Gigabit Ethernet). The wire itself comes in speed specifications, Cat5e being necessary for Gigabit (Cat5 for 100Mbps).

Ethernet is for your home networking on the local side of your router, whereas ADSL is the link from your router to the broadband provider. They are not the same thing, do not do the same thing, and are not compatible. The router handles your local networking; the modem handles the ADSL communication – that they are built into the same box seems to confuse people.

No, ADSL is not the same as Ethernet, you won't get an ADSL cable to fit the socket in your Foxsat, and it wouldn't work if you did.
