I tried with both 0x5a and 0x20, but result is the same.
What do you suggest as the next step? Have I reached a dead end?
yes, there is no success

Referring to this post the following commands were executed (with corresponding outputs). But Error(79) is obtained. What might be going wrong?

What needs to be changed? Any help is appreciated!
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?
dvbsnoop -n 1 -ph 2 -npd 0x20 -b > /tmp/out.bin
dvbsnoop -n 1 -ph 2 -npd 0x5a -b > /tmp/out.bin
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)

You should dump the full raw TS for 3 minutes,so we can analyze the TS on our own.
dvbsnoop -s ts -tsraw -b > /media/usb/raw.ts
Error(22): DMX_SET_PES_FILTER failed: : Invalid argument
dvbsnoop -b -n 1000 -s ts 0x20 > /media/usb/raw_ts.ts
what do you want to?
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.
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.
if you have got dvb-t or dvb-c signal you must learn it hd or sd signal
It is indeed a DVB-C SD signal. Which software applications would I need on a Windows PC to dump full raw TS? Do you recommend using a Linux based computer instead?

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?
No tool in this forum will help you get what you are looking for.
I would say to stop looking
I haven't followed the conversation, but perhaps you could have a look into tsduck.
