Specific testing of the same scenario using all 3 video playback engines in the program you are testing in, and your performance results in whether it made a difference
"Use Windows Meida Player for video playback": Works best with "13.28-beta-2", it plays video with sound, but takes longer to load.
"Use VLC for video playback (recommended): This is my default video playback option. Video playback is not working properly, it's slow and stutters.
"Use ffmpeg": Video playback is not working properly, it's slow and stutters.
Which theme you used during testing while you were testing all 3 video playback engines, bonus points for testing multiple themes with all 3 video playback engine scenarios
I am currently using "Default Plus"

Keyboard and mouse.

If you had any crashes we'll need the whole crash report. If you had a hard crash to the desktop, we'll need the event logs (a lot of times it's multiple logs related to the same crash)
Your LaunchBox and/or Big Box logs
No crashes so far, just performance issues. Shutting down Launchbox I don't see progress pop-up window. I attached the debug log files.
