Ok, this is a weird one. I come across videos on Youtube that will play for like the first 10 seconds, then they just stop. No more downloading...no activity on my internet connection at all. I can pull the slider forward a little and it will again play for another 10 seconds or so. But this doesn't happen on every video. Some videos play fine from start to finish...though if one is playing fine and I try to slide the video ahead the video stops and I can't get it to start up again until I reload the page. Ok, so I'm thinking it's the new Safari with Leopard, so I fire up Firefox and the SAME thing happens. Anyone else having this problem?
