I compared my rips I was making from her channel as they were being produced and uploaded, with those in the collection above, and there is compression in those. They have been re-encoded by someone. I will share mine, as they will be best for archiving. I removed the title names and simply numbered them for the sake of being more tidy. I did not have the missing video above, so add that to these.
I have also found an old forum post that had some of the PH Premium videos in their 4K resolution, but sadly the host is down, and they can't be found anywhere else. I looked hard.
