I can't play videos.

I can’t play videos. Can you help me

Without hardware information like GPU, we can only pray for you.
AMD/NV GPU aren’t be support. For AMD GPU, try the image for magic book: https://fydeos.com/releases/9.0/magicbook

Acer Aspireone AO722-BZ893
APU AMD C-50 Dual-Core
ATI Mobility Radeon HD 6250
2GB RAM

Your gear is too old to run MagicBook image. Radeon(not AMD GPU) needs different video library.

thanks, the way is to try linux
