you've already got all the questions answered
here again in a simple way

here you do not get access
because no decipherable powervu signal is available
powervu has the ca_pid 90 (0x5a) this one is not available here as you can see
it is probably a data stream of either picks up the signal or provides

By DVB rules,first 32 pids in a transport stream are reserved,meaning there should not be any conditional access information in pid 0x20.
Any decent engineer would not setup a transport this way,but of course,some don't really care.

You should get a PMT packet from this stream,where it will say where the ECM pids of each encryption is carried (this is simulcrypt),then you check if there is information in the ECM pid for powervu.
If there is,then you check if the ECM packets are changing every 1-10 seconds,if changes,then you check if there is EMM information for the other encryptions (betacrypt and ***).

If you do not actually find EMM information for powervu is maybe because is using default keys (never updated keys so far),or possibly using fixed keys (you notice this when ECM does not change,control words are the same all the time,found a situation like that once),or simply powervu is not implemented in this trasponder yet.
There might be other situations.

Now,the reason for the error 79 might be just a bad formated command,did you try to just poll for 1 packet instead of 1000?

This part of the CAT packet for the powervu section
{09 12} {0e 00} e0 20 40 0c e0 22 e0 d9 e0 11 e0 10 e0 12 e0 23
I think is a mistake
09 is CA descriptor,and 0x12 is the length of the data,but in this case the data is just 0x10 of data until the next CA descriptor 09 04 17 17 ,easy to see.

The parsing of the descriptor is like
09 04 17 17 e0 63
where 09 is CA descriptor, 04 is length of data, 17 17 0e 63 is data,where first 2 bytes is CA id,second 2 bytes is EMM pid,when pid over 1000 the 0e becomes an 0F (last bit of first byte and second byte is the full pid value)
When you parse the powervu descriptor the length don't match the descriptor.


Many things in this packet could just be misconfigured,the string seem to points to other pids (e0 22=0x22, e0 d9=0xD9, e0 11=0x11, e0 10= 0x10, e0 12=0x12, e0 23=0x13) but all reserved pids except 2.
This might be analyzed at powervu when there is not (because of descriptor is not really a descryptor in reality,just a thought)

dvbsnoop is picky regarding correct command options,so,not uncommon to get errors.

Appreciate the detailed response kebien.

Can you tell me exactly how I can do all this? I'm a beginner in DVB field. Here is a result of scanning a recorded (encrypted) .ts using DemuxToy:

Yes, I tried it. The following commands never finish the execution! (Or at least take a very long time to finish, which I did not wait for). But at least they do not throw any error.

Code: 
dvbsnoop -n 1 -ph 2 -npd 0x20 -b > /tmp/out.bin

Code: 
dvbsnoop -n 1 -ph 2 -npd 0x5a -b > /tmp/out.bin

OScam also seems to analyze this as PowerVu though. Is this relevant?

You should dump the full raw TS for 3 minutes,so we can analyze the TS on our own.
The information you are getting is not conclusive,powervu ECM using pid 0x37 is coming out from PMT we had no chance to see ourselves.
Please post a full TS

Okay, I tried 3 different methods and here are the results:

Code: 
dvbsnoop -s ts -tsraw -b > /media/usb/raw.ts
This throws an error, presumably because my receiver hardware (drivers) do not support it.
Code: 
Error(22): DMX_SET_PES_FILTER failed: : Invalid argument

Code: 
dvbsnoop -b -n 1000 -s ts 0x20 > /media/usb/raw_ts.ts
The output file is uploaded here.

The result of recording for 15 minutes using the record button on the remote control is uploaded here.

Do either of these help?

No,it does not help

I would say to contact a friend to get decent full TS recording,and the way it goes is you would never get any required information with your gear.
It is fruitless.

There is nothing that points out this is a powervu encrypted channel so far.Powervu defines its channels very well,and this one is a mess.

Which equipment would you suggest? Will something like this or this work?

That's interesting. The analysis results are strange then. Why do you think OScam and dvbsnoop are reading it as PowerVu simulcrypt in this case?

which country and which satellite packets & cabel providers?

yes you can use it but only sd channels

if you have got dvb-t or dvb-c signal you must learn it hd or sd signal

Raspberry pi 3 + dvb-c sd tuner you can take full ts record

if you want to simple device ,you must use pc tv card dvb-c tuner with windows dvb players..:thum:

Ok,now make sense.
Is a cable provider.
Their layout and format is completely different,at least the ones I saw.It just do not follow DVB satellite rules at all.
In the other hand,I doubt anyone ever posted or mentioned a powervu cable provider open with the methods used for satellite.Did you find anyone?

A great waste of time and resources in this thread ,so far.
If this would have been mentioned from the beginning would have had a proper response, but withholding information is not the best way to get help.
I find it a bit deceiving.
No tool in this forum will help you get what you are looking for.
I would say to stop looking,nothing wrong with investigation,but wrong in asking help without providing all pertinent information

I did not realize DVB-S2 and C would differ significantly in terms of encryption. The information was not withheld intentionally at all. My apologies if it had any unintended consequences.

Are you absolutely sure about this? It'd be a pity if that's the case. I'm just a satellite and cable TV enthusiast/hobbyist trying to learn new things. It's never enjoyable to reach a dead end...

It is supposed to work with dvb cards in pc (windows and linux), but I haven't tried it.

Regarding enigma2, it works perfectly fine in satdreamgr images (it is included in the image's feed). I not sure other enigma2 teams include it in their image though.

In enigma2 there limitation in live stream capturing which depend on drivers of each box.

In enigma2, I have used tsduck only with ts files as input.

I am in need of the 58.0W Mux Turner 3920H3000 EMMkey. Since the PowerVu Home Edition program no longer finds the keys, it was impossible for me to get them.
