Google's own Chrome browser is supposed to be perfect for Google's own YouTube website.
 
Bandwidth will always be the bottleneck ...

You tube plays great when i'm using Pot with an MGD to back me up!

How about..
4. My work firewall team have banned access to youtube / myspace / facebook etc and it's probably only a matter of time before they find a way to prevent me accessing the Alembic club too!

I have no issues with YouTube on Firefox 3.5.1. I do however have problems with Myspace as nothing with Flash works for me there.

Keith; I think I have read that it is possible that two installations of the Flash add-on might be installed in your Firefox, one being an older version that was never uninstalled.  This might be my problem as well, although the fact that I have the same problems on IE8 suggests otherwise.  I don't know what to tell you to do to check your installation, but I have found it on the firefox site before.  But I never could make sense of it when I tried following the directions and looking at my own installation.  That's my fuzzy recollection anyway.  Try searching the firefox forum.

I have recently come across this site that is trying to improve the internet bandwidth across the USA. We are falling way behind the rest of the world !  http://speedmatters.org

Opera (9.63) browser here.
youtube works perfect for me...I agree that the internet connection plays a role in speed more than the browser

I was experiencing issue #3...called tech help with wireless router company (Belkin) and they updated the version of their software to a more current and by golly it worked...youtube vids loaded fast and played without a hitch.

Dave,
Thanks for the suggestions. I've already been that route to no avail. Deleted all versions of Flash I could find along with Firefox and manually cleaned up the registry. I think it is something with Myspace as I was working fine until they did some updates on their end late last year.

Youtube always works fine for me, I use IE-8 and Safari on my PC and Safari in my Mac.

You tube works great always on my iMac

1 GB isn't a ton of ram, but should be enough.  Is your hardrive almost full?  Is it a wireless connection?  Trying clearing out your Internet cache.

Never a prob with Youtube here, just watched Britney do the Letterman top ten.

I have to say it's #3 for me, using Safari 3.0.4 & Firefox (only sparingly), but the prob might be my 500 MHz G4 with 1.5 GB SDRAM. HD vids seem to stutter alot.

I used to be a #1 - but recently (past several months)not all of the videos are buffering faster than they are playing.  
 
Nothing on my side has changed - Windows XP (xtra pukey) Home Edition Service Pack 3 on a Sony Vaio with a Pentium 4. (Don't buy a Vaio - it was a big mistake).
 
Dave - May I ask why you are polling? Do you know something we don't?
