Your question answers it exactly. I have a HTPC that has a HDMI out and a blu-ray player. No. 3:2 pulldown is a way to shoehorn, and force, and degrade a source into a different refresh frequency. I could do this as a last resort but I prefer to fix the actual cause of my problem. The only problem I have is that the nvidia driver seems to not support 23.976 as a HDMI output frequency. It supports 24. I am trying to get it to go down a notch.
