"C64-Gamevideoarchive 200 - 50+10 Longplays from 1982-84" mentions that the files were recompressed but were they recompressed using the original source (savestate, raw capture etc.) or the already compressed file?
I was also wondering whether I should download all such packs and also the individual releases at archive.org to get a 100% collection? I love to watch those old games being played, and as my Popcorn Hour plays them without problems, I can enjoy them on my comfortable sofa 
Also, are there any savestates available for download anywhere?
Thanks for the great memories!
