Is there anything comparable to Dirpy?
 

Is there any sort of simple free YouTube ripper, like Dirpy was, out there? I can't be arsed to download any software.

Are you willing to install a Firefox or IE extension? I use a greasemonkey script that puts a link to MP4 and FLV files of differing resolutions (if available, ranging up to 1080p) directly on all YouTube pages.

Like an Add-on? Possibly.

Greasemonkey: https://addons.mozilla.org/en-US/firefox/addon/748/

The script I use: http://userscripts.org/scripts/show/25105

You don't have to go through third-party sites. It directly downloads the file from YouTube's server.

Xero, I downloaded that but how can I create it to an audio file?

i use this. just paste the video's main page link

Didn't realize it was an MP3 converter, thought it was just the video you wanted. Sorry. :o

Greasemonkey add on for Firefox works beautifully
