Everybody seems to favour Trash Guides. Just as a counterpoint:
He is super focused on the highest quality available. Unless you’re watching on a huge 4k/UHD screen with professional a sound system, take those guides with a grain of salt. Modify the values to your own screen resolution. If your screen is an older model it may not accommodate more than 1080p or even 720p video anyway.
Bandwidth may also be an issue depending on where you live and what your ISP provides. If so, downloading larger files than your screen/projector affords is a double waste. Go for h265 instead of h264 and save yourself the wait. You can always download them in a better quality when you upgrade your home theatre.
I want to make clear, I would have been lost in the *arr settings if not for the Trash Guides, but man. They’re absolutely written for somebody with ample bandwidth and a huge home cinema setup.
