回複：Help, Please!

If you want to download videos from Youtube, you can add "link" in front of youtube.com address.  For instance, you can change http://www.youtube.com/watch/?v=AEX60VCIp9o&feature=channel to http://www.linkyoutube.com/watch/?v=AEX60VCIp9o&feature=channel and press Enter to the download page.  And from here you may download the video you want.  You need to have Java installed in your computer to do this.  And if you want to convert it to 3gp you can google "free video converter" and download a free software to do it.
