Whenever I'm watching a YouTube video the downstream just stops at a random point (normally at the middle of the video), and whatever I try to do (reload the page, clean cache) I just can't watch the video past that point.

I've Googled a bit and seems that I'm not alone, does anyone know how to fix this?

I'm using Firefox 3.5.5 and I've a 24Mbps ADSL connection, in Portugal.
