If it is offered on some other platform, there might be weaker forms of drm used.
Reversing PlayReady would likely take a lot of work and skill.

I don't think we need to do encryption reversing.
The key is already available.
I downloaded (2) main files:
1. video_file.nds
2. key_file.xml
there was another file that has some information like this:
Code:
"physicalContentId":"video_file.nds"
"keyfileUrl":"http://Sat_Provider_Website/key_file.xml"
"fileSize":1024080871
"drmToken":"AAAEADaQNMCBaRWsfKxlUmvys4GISYjx4FT+rw4kY6YBIndnKYKBu/ykjQVTmsKOTkA/pnrfs0DU0uk="
"drmFree":false
and what about the key_file.xml content itself:
Code:
<?xml version="1.0" encoding="UTF-8" ?>
<Client_ECMs version="1.0"><Total_Session_ECMs>2</Total_Session_ECMs>
<CryptoPeriod Sequence_Number="1"><CryptoStart>5</CryptoStart><ECMStructure>AQAXCOQRW9IL6AAAXl8Q84FwYwAAARaiAjYDAAAA/3Uh4AEAAfwBDAIAgwD5SH4QdRwaK4Q66KD+aJXHi8SesZA0wIHsnbmDZjdy8lC4ImETT/7xnlGEviATpjRS/58XcHEYw5dH8jY87JcFIvz6hRnqWWHtSA==</ECMStructure><Parity>129</Parity></CryptoPeriod><CryptoPeriod Sequence_Number="2"><CryptoStart>720565</CryptoStart><ECMStructure>AQAXCOQRW9IL6AAAXl8VwYBwYwAAARaiAjYDAAAA/3Uh4AEAAfwBDAIAgwD5SH4QKf0TQfW0qdhdEVfLlfRjWpA0wIHsnbmDZjdy8lC4ImETT/7xnlGEviATpjRS/58XcHEYw5dH8jY87JcFIvz6hRnqWWHtSA==</ECMStructure><Parity>128</Parity></CryptoPeriod></Client_ECMs>
Is there any way to use the available information to decrypt the video file?
