For quite some time, about 20% of all flash videos I watch (e.g. YouTube or Vimeo) have been very broken. They become very blocky, as if the stream is corrupted. Here's a still:
I've also uploaded a screen capture to show what it looks like over time: http://www.youtube.com/watch?v=ewcdIOWJNT0
Obviously this makes the video pretty much completely unwatchable.
What didn't help:
- Reinstalling Flash
- Reinstalling Firefox
- Upgrading to the very latest graphics drivers
- Win7 x64
- Firefox 3.6
- Adobe Flash plugin 10.1.82.76
- Intel Core 2 Quad Q6600
- 8GB RAM
- ATI HD5770
Any tips on how to fix this?
