A lot of my files were shitty 480p versions of movies from the Napster days. Now they’re all 1080p, with a few 720p exceptions (mainly tv series episodes). All in all 500 something files in total. Now just watching uTorrent slowly download them all. Hopefully my VPN keeps the eyes off of me…
Install them, point them to your media folder, tell them what your preferred quality level is, and they’ll handle everything else.
The Trash Guides are probably the best resource to get running.
