the pain of decrypting recordings on that weird H6600

[Lordbyte]

I will venture an arm and a leg, and go with ... UnDrm.log ?

I will venture a foot and a hand, and go with ... UnDrm.log ?

u are a brave dude!

hey, i'm trying to give as much info as i can,
till now i didn't knew which logs from where are relevant, u know? sry
i will also go on tomorrow,
thank you very much again!

I will give you a hint. Read about 10 topics related to my different libs. It's not rocket science to guess log name

sarcastic as usual
exactly that choice of words is the reason why u think i am being rude
i am a really nice guy indeed, except somebody is talking down to me for no reason

i am just about testing right now, and my problem is that i don't get a .ts file out of your script at all..
is it only the magic value, with which i have to experiment? or is there somethang else i can take a look at?
u told me that magic value "1" should nearly allways work...but it doesn't..

libUnDRM.log is allways telling me this:

why does he allways have a problem opening a srf file? what could be the reason? im wondering

[Lordbyte]

Verify that 20151125122109.srf really exists, and can be played back by TV.

Also, make a new recording ... 45 seconds or so .. and try that one also

[blendstylez]

of course i checked if these files exist..but they do! and get played with no problem with the TV!

this is a 30 minutes recording..the last tests i did was with a 1 minute recording..just to let you know

can the CI module play a role in this context? i don't think so..i am fighting with the tv side encryption from samsung so every recording gets encrypted, no matter what the signal may be or contain right?

-d is Debugging on, -A is what?, -l is path to library

I have no idea right now ... I do notice that a key has been created by root process ... 16 bytes

Or did you put key there to test something else ?

I dont seem to remember H-models being able to create a key-file.
If it could, I would be running the PVRDecoder in E/F-mode

H-mode was created because "we" couldent get hold of key ...

i thought the same, but i think it is from the DRM offline decoding library i also installed...

maybe the access rights to the srf file aren't correct?

[Lordbyte]

-A and all the other switches is documented in the sectroyer SDK available nowhere.
It is clearly of special use for geniouses and holders of the universal secrets.
You are not ment to understand, you are ment to obey, goto work and pay taxes.

This is your chance to rise against the gods, declare your independence, install IDA, hack the shit out
of the libraries, figure out whats going on .. Improve on it .. release it .. taunt gods .. cash in .. check out.

The life of a hacker is a most interesting one, I am told

So, change those access-rights .. Did it help ?

If no .. did you need to ask ?
If yes .. did you need to ask ?

Why dont YOU tell us if it made a difference ?
Or do you expect me to go borrow a H-model and test it for you ?

Man, - get IN the game, or get OUT of the game.

[blendstylez]

hm ok..
i understand..sorry for wasting the time of all u guys here..

so if i am unable to do it by myself, i should step out of the game..
seems that i pissed you off as well

i tested to change the rights of the key file, but that doenst change anything, and as far as i understand the srf has allready full rights for all groups..
maybe i am just too dumb for all this..excuse me!
i am speechless by now..got no more to say

[Lordbyte]

No, I am not pissed of ... at all.

But I, like sectroyer, do not expect simple boolean questions.

"Should I try A or try B" ... In my opinion you try both, learn what is to be learned,
and some day here on forum you can say stuff like "I tried that, and I advise you to do B"

You seem so unsure on your feet, that even the smallest effort seems daunting to you.
Do you have the mojo and jedi to hack your TV, carry on ... But is your heart in this ?

Or are you just like everybody tell me that everybody has become here .. just looking for service, and bye-bye mam

I told you .. sectroyer demands attention and work ... Me less so, but still
