Hi, this looks ok - the videos that don't show are either videos that do not exist OR more likely videos that don't have the same name as the display name in attract mode. The display name is the name you give for the display of a given emulator you use. So let's say you configured attractmode to use MAME as an emulator, the display name you give for MAME can be "Arcade" for example. This means that the Hyperspin main menu theme mode will look for a video file called "Arcade" in the themes folder. BTW, you should consider using the latest version of Attractmode. 2.2.1 is very old and theme designers like me code for the latest version. It can solve many issues you might encounter.
See the screenshot, same name for the video files and the displays:
