In this episode, Sheldon becomes fascinated with a peanut butter and jelly sandwich that he believes will make him smarter. Meanwhile, Georgie tries to help Sheldon overcome his fear of a boy scout who bullied him, and Missy deals with a crush on a boy with blue eyes.
I'm assuming you're referring to the TV show "Young Sheldon" and specifically the episode "S01E05" with the file extension ".bdmv" which likely refers to a Blu-ray Disc Movie file.
The fifth episode of Young Sheldon's first season originally aired on October 26, 2017. The episode was written by Steven Molaro and Tami Sagall, and directed by Lee Aronsohn.
However, I couldn't find any information on a specific episode titled "bdmv". Instead, I'll provide you with some general information about Young Sheldon Season 1, Episode 5.
