I use Pazu Netflix Downloader. No screen recorder.

Sigh... If you do a search on the forum, you will see we have already discussed that this is not a WEB Downloader but a WEB Ripper.
These record at high speed but it is not the original file like what you get from StreamFab.
Once StreamFab is fixed, download that same episode and you will see it is not at all the same. You can do a diff with WinMerge but you will see the difference just with the file size and the codec and encoding settings displayed in MediaInfo.
Here is an example of what to look for that are telltale signs it's not a downloader:

I have it installed from way before as i wanted to test it but trust me they would have made a big announcement if they switched from recording/ripping to actually downloading.
- Video Quality of High/Medium/Low or having Video Quality at all for that matter
- Using Hardware Acceleration
- Conversion. Why convert if you download?
