PUBLIC MARKS with tags qualité & youtube

Try this: When viewing a movie on YouTube, add &fmt=18 to the end of the URL. In addition to slight video improvement, you should also notice increased audio quality. Notice I use the word “slight.” I hope YouTube goes further than this humble baby step towards something more like Vimeo’s level of quality. There’s also a Firefox extension that supports higher-quality YouTube playback (among a list of other enhancements).
