And BTW, looking at your last log, the IP 127.0.0.1 is the loopback address FOR YOUR OWN COMPUTER :-)

Find TV IP-address and correct it in PVRDecoder settings, before PVRDecoder can work :)

It's not the same guy, but that's what I meant by:
setting an arbitrary localhost FTP server IP

Thanks Zoelechat and Lordbyte for information ...
If I understand correct, decrypting without connected and rooted TV is not possible for PVRDecoder :-(
Could you, please, give me a tip for any (free or commercial) application which can decrypt/convert USB-recordings without connected TV?
It is in real off-line mode.
Thank you in advance, Mylosh B.

Read my lips - Decoding recordings without root access to the TV that performed the recording(s) is IMPOSSIBLE.
Only the TV "knows" the decryption key(s) for the recordings, and there is NO software in the world that can decrypt
AES-files without the correct key ..

But when the PVRDecoder is allowed to command TV to generate the key(s), the keys can be "downloaded" to the USB-device,
and after THAT point, the off-line decoder have no use for the TV anymore ... now keys are present on the USB-media and
the off-line decoder can handle the rest ..

But the "sneaky" point is that ONLY TV can generate the needed keys !!
Thus .. There is NO way to decode anything unless TV is rooted ... to obtain keys :-)

Thanks for info.
But I think, that some commercial (payed) tool must exists for off-line converting :-)
This tool knows Samsung's keys for decrypting of recordings, because Samsung's programmers are only people and they use of standard crypto-methods.
And producers of "video-converters" are also clever and they create decrypting tools for many TV systems ...
It is the same as virus nad antivirus business.

There is no single "Samsung key".
Each individual recording use a private key derived from a TV internal crypto-engine.
This internal crypto-engine has been securely implemented, and the reversal of the HARDWARE-crypto-engine
is way way beond what you can expect to EVER become reversable to amatours (us).

So, in other words .. I will win both the world championship in *both* Boxing and Formula-1 the same year,
100 times before any chance that you find ANY single key for ANY single recording without access to TV crypto-engine.

Sorry dude .. No "golden key", and no tools to help :-)

Even if we reverse "hardware" engine we will still have to dump "hardware key" (all other keys are decrypted using this one) and in order to dump you still would have to root your TV :)
