I don't know why, but I have the world's worst time with buffering of flash video and I have to say that vimeo is a major offender. I'm using a G4 Mac which is old, but I wouldn't say ancient. In any event, vimeo and metacafe tend to stall during the buffering process. (I have fewer problems with YouTube and Hulu). This is absolutely infuriating, because there is no help for the situation other than to refresh the page and start over with no guarantee that the buffering won't stall again. I can sometimes locate the site and try to download the .flv file directly, but trying to do that now with the vibrato .flv isn't working - the download process starts, gets slower and slower and finally stops before the download completes.
Anyway, any chance you can post on YouTube instead of vimeo or (even better) split long "quick" thoughts into parts (that way if the buffering stalls I wouldn't have to start from the beginning).
I'd love to see the vibrato video, but it just isn't going to work at the moment.
