I have hit quite a few dead ends looking for sites which convert a youtube link to an alternate format for offline viewing. To clarify the site must: 1) ask for a url (youtube) 2) convert the video to some alternate format (i.e., NOT just a script to retrieve the flv file. 3) produce a link for you to download the resultant file (preferably the user should NOT have to provide their email) 4) be free. 5) be popup free (tall order?) I searched here and found more dead ends (maybe I didn't look hard enough?) Can people post their favourite websites that do this. I just tried zamar.com but it has two knocks - popups and requests your email address. It did a nice job of converting flv to avi (mpeg 1 according to avicodec) though.
