I have watched that video thru the tunnel, very high quality.
Sometimes when I watch video clips on youtube, there is a lot of what I think is called "buffering" when the video stops, and a twirling circle appears, then perhaps the video continues for ten seconds and stops again. Is this to do with the speed my computer runs at? Your video clip played straight thru without any pauses.
I am asking this because I am thinking of buying a laptop, so is the speed crucial, megabits per second? or the size/speed of something else. I like to watch videos clip from a particular site, that seems to become unwatchable because of the "buffering". I know this is slightly off-topic but you seem to know about these sort of things.
