It seems to be working for me. I had two problems on the one show I wanted to download:

• The download1 link didn't work, although the download2 link did. I don't know how to fix this.
• I was dumb and had to go look at the error console to figure out that it wasn't going to work with NoScript blocking scripts on ustream.tv!

Thanks very much for writing this, yager!

If you look at e.g. http://userscripts.org/scripts/diff/42631/84210 you can see that this guy is uploading a "new" identical version of his script several times a month. This is the kind of behavior someone would engage in if they wanted to make it hard for someone to notice if they eventually included malicious code in the script.

Also, it doesn't do anything you can't do with a bookmarklet; it just inserts a link to linkyoutube.com.

I haven't installed the script; I'm just looking at its source.

This script just adds a link to youtubeloader; it doesn't do anything you couldn't do with a bookmarklet, except for only displaying the link when you're on a Youtube page. (I haven't installed it; I just read the source.)
