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

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

thanks, the way is to try linux
