Does anybody else have a problem loading Youtube videos?

For the past couple of days, certain Youtube videos won't buffer.  I wait for them to buffer and they never do.  If I get lucky they actually run in 240p, but that's low quality.  Is there any way to fix this, or is the problem on Youtube's end?

I have no problem loading 720p videos, even some 1080p play smoothly. Sometimes YouTube's servers are slow, but it's mostly your ISP. I have a 6Mb connection from AT&T U-Verse.


UPDATE: [s]Just watching a NCIX video, and I'm trouble loading 720p; barely getting 480p smoothly.[/s] Nevermind, just realized I'm downloading 3 games on Steam.

I never have to buffer... then again, i'm on a 500mbit fiber line

Today I realized that Youtube videos run better if you ditch the flash plugin and switch to HTML 5.  You can do that here:
