This is my first post so please bare with me if I did something wrong unintentionally.
That other day my friend tested the recording function of his Smart TV from LG, model 42LV5590 and it all went smoothly.
AFAIK every TV manufacturer is obliged to force some kind of DRM encryption and using proprietary formats, just to make sure all recorded material is only playable on the same device that has been used as a recorder, e.g. no export option.
My only wish is to have the DRM-cyphered file and demux/convert/remove the DRM in order to be able to play it on my personal computer as a normal video file, lets say .mp4 or .avi container with .h264 and aac streams.
Because there was a TV show with my humble appearance, i kind of want the video for my personal colelction, and i have no intentions of selling it or doing anything illegal with it.
The TV uses JFS+ filesystem and has some modified Linux distro.
Moving the files was a pain in the ass, but he succeeded.
For each TV show segment that was recorded, the TV makes a number of files: .PIF .IDX .STR .THM
The video itself is the biggest file, STR.
G-Sort Recognizes it as MPEG2 Transport Stream Video/mp2t, but i cannot render it in VLC, nor can i convert it using a number of tools for video conversion.
I have the obfuscated certificate used to DRM cypher the video, as well as the template for the cert (extracted from the TV itself.)
Now all i need is some expert to put the pieces of the puzzle together and help me get rid of the DRM.
I tried free2me software (command line mode with no luck).
I can provide you with sample footage files as well as the certs. Please help me solve this stupid issue.
Thanks in advance.

About two years ago I've posted in a brazilian forum how to extract this videos.
But most of people don't understand portuguese
Because this I've created an English version:
It seems it work by you? But if I use your STR-files (from 19th April) and also the files in your link (http://servbg.com/LG42LV5590/) the TSDoctor says "TS-files encrypted".
TSDoctor says the same with my STR-files out of HDD-recording with 47LM960.
Is there an additional trick how to remove the encryption?
Thank you in advance
TS Doctor says "File is encrypted. Process aborted!".
How the encryption is removed? How can I extract the certificate from the TV? I'm without luck just like @Sharandriver I hope you'd see and give a hand. It's really frustrating to have the recording but unable to do anything with it except watching it only on TV!
I have a 47" LG TV which saves files recorded from the TV onto a USB hard drive. I cannot find a way to convert these files into a video file that I can play on my PC.
I also have tried TS-Doctor and get the same "File is encrypted. Process aborted!" message.
I also have tried Kernel JFS Data Recovery Tool which cannot find the partitions.
This is what the structure of the drive looks like after the files have been saved.
If any knows what to do with them, or can provide a link, please do so. Your help will be greatly appreciated:
Were you able to get an answer? I need to convert the LG Smart TV files to a more common file format as well.
i can't did it, not work!!
please help? why not work?
Recently, I read about LG TV's encrypting their recordings (tried to find the link, no luck yet). It seems that each TV has its own private encryption key, a recording from one TV can't be played on another. There are a number of sites dedicated to hacking LG's firmware. The TV's key would have to be retrieved to decrypt the recordings, but so far it looks like they're only able to enable features. Also, many of the links don't work anymore.
which could solve the problem
Well, it does (only) seem to be a dead end for now, - but that was also the case when I started developing the Samsung PVRdecoder for series ES and F.
As some of you may know, the tool went public years ago, and continue to work correctly to this day.
As fate would have it, my last Samsung TV (PD64F8505) have now gone competely dead, and thus bye-bye to my Samsung development environment
I have grown tired of Samsung and their choice of substandard components .. and I wanted OLED
Now I am the owner of a LG OLED65E6V ... Who want to play ?
You guys tell me all you know about obtaining root/ telnet / ftp / any knowledge,
and I will port the PVRDecoder to LG ...
Anyone up for some fun-hacking ?

hello, in 2020 did you find any solution to this problem?
Pity someone from LG doesn't come here and spill the beans on how the encryption works.
But what a nasty thing for LG to do, anyway! Why stop people playing what they've recorded from their TV on other devices?
Next, I'll find an LG forum and kick up a fuss - tell them what I think of them.
