made a little progress but i still haven't got it.
here is what i got this time:

$ movgrab http://m.youtube.com/watch?v=OzyI52
mb2Io

Formats available for this Movie:webm:854x480
ERROR: 403


Selected format item:3gp:400x240

/ $

which is generally the best format to select for playing videos on the phone? the QDL app works fine i just trying the movgrab for fun.
