This is amazing! ^^
Does exactly what it's meant to do and does it well! :)
Great job!!

I LOVE this script! It makes all the Youtube videos high-quality and things so that I can actually hear close to what the original sounded like. You can also combine it with a video download utility to download HQ versions of music videos. It will refresh the page with a &fmt=18 link if the link doesn't already have it, which sometimes gets annoying, but you can't complain much when the script does what it's supposed to do. Good job! ^_^
