Do you experience problems during downloading?
Check your connection in Status and Interface settings window.
Use Test Server in Config > Servers.
We will probably ask you to do a test using only basic settings.
Do you experience problems during repair or unpacking?
Enable +Debug logging in the Status and Interface settings window and share the relevant parts of the log here using [ code ] sections.

Anything below 300MB is not renamed.
This is meant to avoid renaming auxiliary files like NFO etc.
The threshold is rather low, because I do see episodes around 180MB.
