It seems Sony have made it impossible to archive off any recording from the PVR and watch or edit on a PC.

If anybody knows of any proven decryption method I would be very grateful.

As required by the copyright holders - but as I understand it discussion of such illegal activities isn't allowed on these forums?.

So why is it that ,I understand, there are recorders out there that do not encrypt the recordings made from public broadcasting.

Loads of them, HD recordings are encrypted in the box, no reason why SD ones need to be.

Off the cuff list of some boxes that allow archiving of SD recordings to a usb port that are playable on other devices.

Freeview

Topfield 5800, Humax 9200, Humax HDR FOX T2

Satellite

Humax Foxsat-HDR.

Copyright law forbids the recording of broadcast TV programmes. There is an exemption for timeshifting, ie making a recording in order to watch it at a later time.

However copying said recording to some other medium to keep for repeated viewing as part of a collection is illegal without the express permission of the copyright holder.

Which would technically make the Panasonic Freesat+/Freeview+ Blu-ray recorders illlegal. They are allowed to make one copy to a BD disc. Not much point if you are legally only allowed to watch it once

I think you have proved my point that the whole thing is utter nonsense.

I still believe, contrary to what one contributor believes, that it is possible and not illegal to circumvent the ridiculous encryption imposed by Sony.

Buy a different make maybe? I feel your frustration though, I'll just have to keep hanging on to old(er) AV gear.

You mean imposed by the copyright holders, Sony (along with other responsible manufacturers) comply with their requirements.

It's about time the copyright holders gave up with this nonsense. We've been recording tv onto tape since the seventies and that wasn't just for timeshifting. I'm sure everyone has a tape of something that was broadcast in their possession. So we're all lawbreakers. Ridiculous situation.

The format used by most Sony PVR units is linux based, if it is one of the more recent models (SVRHDT Series) then the best approach is to back-up onto an external hard-drive which the PVR will format, once you have completed this use one of the many linux live boot iso`s to boot a PC with linux and then connect the external hard-drive which will now be visible. Finally copy the required recordings across to a drive or partition that you can access later with windows.

A little long winded, but does work!

Good luck

Andrew

Thanks for the suggestion. I am sure, a long time ago, I tried just that method. I do have a Linux system as well as Windows 7. What you are saying is that by doing that the recordings magically become visible? I will try and if it works I will report back findings.

My Digital Stream PVR allows me to transfer programmes to an external HDD.
The SD TV and Radio are not encrypted. I have successfully copied them to my PC (using Kubuntu) and I can watch/listen or edit them. The HD programmes are encrypted so I can only watch them on the DS.

I am a bit puzzled because I tried to copy off an SD recording onto a USB hard drive and then open in Ubuntu. Complete failure! Am I missing a step here? Ubuntu sees the files (4) but will not open in either the generic Movie player or VLC.
Any thoughts?

Make sure you copy the files across to a fat32 windows partition, then boot into widows (I use Win 7 x64) and content should be available even through windows media player with appropriate codecs installed.

Good luck

Why FAT32 . A PC will transfer data between any drives it has a driver for. NTFS should be just fine, all the versions of Linux I have work with NTFS (Slax, Ubuntu). If the pvr drive has a linux filesystem then installing EXT2FSD should allow read/write access within windows without booting into linux.

I agree - these copyright fanatics are living in a timewarp. Sony was on my shortlist for a freeview recorder but is now deleted.

You can believe what you like, but it is plainly illegal, and in some cases is a bone-fide criminal office with a prison sentence (rather than just a civil tort you can be sued for) as the maximum punishment.

There's not enough jails for those of who have been using vcrs for years . It's an offence to reverse engineer an encryption algorithm. If there isn't one and there is no reason for SD content to be decrypted it's perfectly legal to record it.. The content is broadcast without encryption.

Not suggesting you flog them down the car boot, that would be illegal. Basically you are saying if your Auntie Nelly is on the Telly and you recordd it and keep the copy and show it more than once to your family it's a criminal offence

Get a sense of perspective for heavens sake

By your definition Panasonic UK is aiding and abetting a criminal practice by allowing a single copy of HD content to a blu-ray disc. Ridicolous argument.

My DS puts a file extension of .trp on the SD recordings.
You could try changing the file extension you get on the Sony PVR.
I hope this helps.

Not quite.

Technically it is illegal to do anything other than timeshifting, however no one in the UK, not one person, has ever been prosecuted or sued for archiving stuff for their own use. Even if they did, it is a civil offence, but it is something the authorities turn a blind eye to. Just the same as copying a CD to an MP3 player, again technically illegal but you wont be sued for it as long as it is for your own personal use and not distributed.

Only commercial copyright infringement is a criminal offence.

There are a number of Freeview PVRs that allow archiving of SD content to an external HDD, including the Humax HDR Fox T2 and Digitalstream HD PVRs.

The Humax can be fooled into decrypting HD recordings too but it's a bit long winded as it involves copying the files off and on again and custom firmware/application.

The filesystem used by the Digitalstream and Sony Freeview HD PVRs is XFS not Ext2/3 (the Sony and Digitalstream machines are based on the same platform so are almost identical under the hood, with Sony adding some customisations to support Bravia Sync). No XFS drivers exist for Windows but there is ONE program that can read an XFS drive on Windows, UFS File Explorer but it isn't free. The cheapest way is to either use the Samba Mod created by DaveGU over at AVForums ( that adds Samba sharing to the Digitalstream, this allows you to copy files on and off the machine, stream to the PC and other media devices that can see Samba shares via your home network ) or use a Linux boot disc. However, Dave's Samba mod doesn't support the Sony simply because Sony haven't amended the firmware to allow user modifications to run which Digitalstream did do at the request of users.

Update.....I have tried to copy from my Sony HD PVR onto a USB drive, formatted by the unit, a number of SD recordings. I can see that the drive is XFS format. Trying to open in VLC or the generic Ubuntu media player does nothing. Each recording seems to have four files associated with it.

I think I will sell the Sony and get a DigitalStream or a Humax. Either has to better than the c**p Sony! Never again.

So you buy a PVR that does EXACTLY what it's supposed to, and EXACTLY what it's required to - and then complain it's preventing your piracy! - bit of a cheek

.
The Digital Stream PVR creates a folder with a number of files inside. The largest one is the programme and the others are programme information.
If you change the file extension of the largest file to say .mpg you may be able to play it using VLC.

The largest file is the actual recording, usually with a .TRP file extension. You could try changing the file extension to .MPG to see if it will play.

I certainly have no problems playing the TRP files in VLC on Windows 7. I use DaveGU's Samba mod to copy the files to my PC via the network, and then just play them.

However, you will ONLY be able to play SD files. The HD files are encrypted, so even though you can copy them to a PC you cannot play them. Are you sure you are not trying to play HD encrypted files?.

However, it could well be that the Sony encrypts all files including SD (for some reason some PVRs do even though they are not required to do so), which would certainly explain why you cannot play anything on your PC.
