Downloading some HEVC versions of episodes, and download rate slows to less than about 2 MB/sec (though mostly around 1 MB/sec).
If I download a non-HEVC episode it's anywhere between 15 and 35 MB/sec (almost maxes out my connection).
As far as I can tell, there's nothing unusual about the HEVC release - there's rar files, roughly 14MB in size each, made up of around 20 articles each file. Some articles fail so some repairing is needed, but many are successful and repairing/extracting doesn't seem to make a difference.
I've tried DirectWrite on/off, DirectUnpack on/off, DirectRename on/off, but those don't seem to make a difference.
Even if there's no repairing/checking/extracting happening and it's just downloading, it still slows to the less than 2 MB/sec download rate.
Any ideas what I can check for?
