Recently I reinstalled Handbrake to Linux (Pop OS) hoping to start ripping
DVDs again. Previously it was a deb package but it appears Handbrake has
moved to Flatpak for Linux distribution.

This version of Handbrake is not working for me and I'm struggling to
understand what I am doing wrong. When Handbrake scans the DVD it does not
find anything. I have to open and start the DVD in VLC and then Handbrake
it will find it in its scan. What it does find shows as pixelated in both
the preview as well as any rip it makes for me. I've tried a handful of the
presets and no matter what I chose I get the same pixelated output.

Are there any other Flatpak/Handbrake users in this group that have it
working successfully for them who can give me some guidance?
