Hear it in context
Notice where the phrase sounds natural.
It keeps buffering every two minutes, it's doing my head in.
Give it a sec, it's just buffering.
Fix the pattern
One small grammar move makes it sound right.
Don't say 'the video is buffered' — when it's stuck it's 'buffering' (the -ing form).
