I've been using handbrake for a while now, Especially the last 3 years as I've been digitizing my DVD/BD collection for use with Plex. Over this time i thought i had settled on a "preset" after alot of reading, but i believe i had 1 mistake that may require me to start over.
When choosing audio tracks i had been down mixing the main track to AAC Dolby Pro Logic II and the main track again using AC3 Passthrough for compatibility without having to transcode.
Just this week I decided to upgrade my TV to 4K and finalize my surround sound setup. It seems that i am getting surround sound when playing the movies, but I'm wondering if the choice to do the second track like a did was a mistake?
If it is "wrong" I have alot of re-ripping and encoding to do. about 3 years worth

I would appreciate any comments or suggestions.
HandBrake version (e.g., 1.0.0):
