The extraction engine is only used by the monitor feature and when you enter a url in the "Enter (or Drag and Drop) the URL of a video page to download" text box.
This method only supports around 100 poplular sites that can be captured by extracting stream urls from the site.
AUTO mode, DVR and Audio Recording do not use the extraction engine.
Dont forget sites change all the time, and when they do new extraction engine updates are required for the monitor feature to keep working.
In most cases auto mode will work (unless a new protocol is released that JMR doesnt support). And there is always DVR and Audio Recording modes for those sites that are not possible to capture from via direct download.
If you have sites failing then please let me know which site and I can look at supporting what has changed. Debug logs are good as well.
