I have Fusion 3.0. All of a sudden, any video doesn't play in the browser on the host (Mac). However, when I play the same on the guest (Win7 X64), it shows correctly. I tried it on YouTube, Vimo, etc.
Do I need to check a setting?
If it were the other way around, it'd be a fusion issue.
Have you updated flash on the mac recently? If not, try doing that.
I too would have suspected that. The thing is, it has been working so far.
