Option boxes for Video, Audio, and Subtitles are too small

[joobert]

Describe the bug
The option boxes to select the video, audio, and subtitles for your media are too small in some cases. The text gets cutoff prematurely after a certain number of characters, which really takes away from the polish of the rest of the theme. Keeping the current size as a min size, and then dynamically increasing the size based on excess character count would fix this. (Sidenote: In the screen capture, you'll also notice the clearlogo is misaligned. I've already created a separate issue for this.)
