Not sure what you are asking.
For checksums,they are incorrect for the CW given.
CW: F4652D98B7C624B1 checksums would be 86 and A1.
Plus,not sure but apparently the CW are changing from odd to even,so this is not a biss feed.
I would say you need to provide a lot more information about the feed,how is encrypted (since is not biss),and what are you trying to do.
For an hour long encrypted file you would need 360+ CW's for the slowest systems.

You must try to write good english,because what you say makes little sense.
How can your data be correct when cheksums are wrong?
How could you think to use rainbow tables when is not BISS and CW does not have checksums?
Do you understand how RBT works? it can never find any other type of CW that is not CSA,and CSA has checksums.
If the video is not CSA encrypted you must first define how is encrypted.
Without more information is impossible to help.
And I suspect you don't know what you are doing : you using rainbow tables to find CW that have wrong checksums? Rainbow program will NEVER give you a correct CW without correct checksums.

Very interesting. The .ts file is 13 seconds long. It is not BISS but Videoguard from 19E. CWs change every 5-6 seconds. Even though it is CSA, the CW checksums are wrong. The file properly decrypts using the CWs with the wrong checksums. If the checksums are corrected, it doesn't decrypt.

It's for sure CSA and it's allowed to use all 64bit in the key without the checksum.
This rules out RBT, CUDAbiss and many other CW finder programs and makes the searchtime way longer = no realistic for now

DCW CRC is wrong simply because it could be CSA 2 ( 64 bits ).

I have also tried this method of recording .ts file and I can get crypt8 and key out of CSA rainbow but it will never wwork I think and this is the message from oscam log.

Card [videoguard2] use k1(DES) for CW decryption in unique pairing mode.

DES key is needed and not CSA.

The data send to the card over air does use DES or other encryption depending on encryption system.
Then the card decode the ECM to a 64bit CW which is send to the CSA DVB algo to decode the ts in real time.

Try to put in F4652D98B7C624B1 in VLC under advanced preference demux/mpeg-ts/CSA key + second CSA key and play the ts posted above and you have clean picture.

Most of all encrypted DVB on sat / or terrestrial does use CSA as the underlying ts decoding 48+CRC / 64 bit

The 48 bit is a restriction from back time when CSA original was released due to export rules.

The thing with RBT is it only made for 48bit+CRC if you should make it for 64 bit if should be 65.536 times bigger tables
Also next problem is that the stuffing are removed on more and more ts which roles out RBT in the future

Ok,now we are talking.
Most 99% of the services using CSA only need a key 48 bits,which is the grounds for ALL the key searching tools we are currently using.
This is the only reason we can find keys in a reasonable time with the processing power we have today.

Now,is way different to brute force 64 bits,and I am surprised they are using all bits of the key for this sevice.

So,basically,we are dealing with exponentially bigger search times,and CSA has not changed,is not CSA 2 oe 3 or whatever,is just using al available bits of the key for data.

So,the question I am obligated to make is how did this CW were found,since original poster said RBT was/can not be used.

For the layout described in the post,it doesn't show the even and odd CW in the same line.I have never seen an ECM that does not carry both at the same time,so this leave out ECM decryption.
So if this was brute force,how long it took to find them,and of course what method was used.
Pretty new and cool stuff.
