I took a look at the YouTube API, and, unless I'm missing something, even it doesn't expose a method or property that gives the exact URL of a given YouTube FLV video. The API will give you all kinds of information about a video
except for the FLV location. See the following URLs:
http://code.google.com/apis/youtube/...ng_Video_Entry
http://framework.zend.com/apidoc/cor...ideoEntry.html
I guess I'm disappointed, but not entirely surprised.
