After researching, the best solution I found is Leawo Prof DRM, it's kind of annoying to order on their site because by default they have a lot of other things checked, you need to uncheck everything and check the "Lifetime" button for the "Single function module" item called "Prof DRM Video Converter". It's $30 USD but works for iTunes in 1080p and when I put some HD content I purchased on iTunes through, it went rather quickly, I believe it is not re-encoding (hard for me to tell). This is the link to the page I'm talking about:

Edit: I looked on their site and there's a coupon code active now (12/5/21 US date orientation) that takes off 30 percent, it takes this software to just under $21 USD. You can find it on their homepage or copy this and paste it in at the checkout screen: LEAWO-30PCT-OFF
