Does anyone know if there's been any recent success in understanding the encryption used when recording HD files? It's a real pain having to go to non-Freesat mode and manually record to avoid the encryption for BBC HD and I've never worked out how to get ITV HD in non-Freesat mode.

It's all gone very quiet on this topic of late.

You can't get ITV HD in non-freesat mode and the encryption is stb specific. An encrypted recording made on a hdr will only play back on the hdr that recorded it.

It doesn't help for ITV, but aiui for most BBC there is now no restriction on copying most programmes, and for the rest (US films?) there is the facility to copy once.

I don't have a humax freesat box, so this is only what I've picked up. I'm happy to be corrected if I'm wrong.

On actually overcoming the encryption, as far as I know no-one has had a crack (forgive the pun) at it. There has been some analysis of the sidecar files that amongst other things set the copy flag (as grahamlthompson knows better than I do ). They are trying to do the opposite and get non-native files to play on the HDR, and this is a side effect. I don't think it improves on the current options re encryption though.

They're still encrypted though, so you can't play them on a PC, even if it does let you copy them.

So that is to say you can copy them to blu ray only--correct?

Well, you can copy them to your PC, but you'll have to copy them back in order to play them.

The Panasonic will let you burn them to blu-ray yes, but last I heard there were a load of problems getting the discs to play back on normal blu-ray players.

OK--so there's a tech really worth the money then.

Something i might try soon on this topic,

Transfer a HD recording to my PC,
encode it to a bluray or dvd structure
make an iso of it
Mount it with a virtual drive,
Run AnyDVD HD on the virtual drive to see if it recognises and Cracks the encryption.

I think the chances of this working are close to zero . The encryption key is unique to each hdr. An encrypted HD recording won't play on any hdr, only on the hdr that recorded it.

I've tried something similar byngo, but to no avail.

I've also inspected the encrypted ts file and it in no way conforms to any ts standard, suggesting that it's been encrypted at a low level. I had a quick examine to see if the encryption method was very weak, and sadly it wasn't!
