For the sake of elimination, can you provide your
line stats please so we can see what speeds you should be getting from your line.
However if you are getting around 1Mbps download on a speedtest, this should in theory be enough to buffer a youtube stream.
That said - something I and others have observed for a long while is that lesser popular vids seem to be given less priority.. and on occasions even I see slow buffering and thats on a 24Mbps connection.
Another check can you test this video as this is a 'popular' and is coming down from Youtube at a steady 576kbps and shouldnt have any buffering problems.
