Some notes on the Samsung UE40C6800 TV, PVR, decoding the PVR recordings and SamyGO extensions
Posted by jpluimers on 2014/09/10
After having recorded quite a few broadcastings to USB from my Samsung UE40C6800 TV with the T.VALDEUC 3011.0 firmware, I wanted to copy them over to either a Windows or Linux based machine for post editing.
Then I found out the USB device had been reformatted into XFS, probably because of its Guaranteed-rate I/O.
The first post I came across (SettoreZero: XFS filesystem and Samsung LEDTVs) indicated XFS is supported under Linux, but not under Windows (it appears the latter might be true).
So I went collecting useful links on which I will start doing deeper research in a few categories.
As it looks now, most of it will probably lead to various Linux shell scripts based on SamyGO.
General info:
XFS documentation:
- XFS Wikipedia External links.
- XFS.org.
- SGI – Developer Central Open Source | XFS.
- XFS Papers and Documentation – XFS.org.

Limux support:
- Linux Distributions shipping XFS – XFS.org.
(which means openSUSE – the Linux flavour I use most – supports it) - BusyBox.
- SamyGO • View topic – Are we sure firmware is still Linux based?.
- xfs_repair(8): repair XFS filesystem – Linux man page.
Windows support:
- XFS Data Recovery Studio recovers files from hard disk.
- UFS Explorer Standard Recovery.

Even if you get to read the contents of the XFS partition on your computer, you won’t get any further. You’ll find that the files containing the audio and video are encrypted with a key that is inside a chip in your TV. The contents of your disk can only be played on your TV, not even another Samsung UE40C6800 can play it.
To read the XFS filesystem I’d suggest booting from an Ubuntu live CD. This will let you try Ubuntu linux without modifying your current installation. http://www.ubuntu.com/download/desktop

Thanks. That will save me a lot of work, as I planned to see what would be playable on a different device.
