I'm using the latest version of Handbrake on a PC. The problem I'm having is using the presets. I have read numerous threads on suggested presets. What I can't figure out is how, on the "Picture" tab; do you change any settings. They are always greyed out and don't give me an option to change anything. Also when I do make a change in a preset; how do you get Handbrake to save that setting. Every time I make a change and close the program and than re-open it; my changed setting has reverted back to what it was in the preset. I have even tried building a custom preset and I have the same problem with that. What am I doing wrong????
