I can only speak for myself.
I re-encode all videos in HQ x265 format. This is my own work and takes up a lot of time. This is not a simple quick re-encode. Many people dont want huge 15GB videos for their collection.
To say too old and new: I'm starting a collection with the oldest to the newest, as far as I can get the original source.
Please compare the quality of the videos before venting your frustration here.
Oh well, as long as the download rate is that high, I'm not doing anything wrong, right?
