I know there is a lot of sites explaining this converting and downloading, but i like my own understandable way.

To use it one any Youtube video just type “&fmt=18”
To embed in player use “&ap=%2526fmt%3D18 ” which is the same as upper code, but only works in embedding.

For example :

High quality

Normal quality

Ok now where to

download youtube videos

1. Zamzar.com – Convert and download youtube videos

2. Keepvid.com – save your videos to disc in .flv and .mp4

3. Vixy.net – It allows you convert a Flash Video / FLV file (YouTube’s videos,etc) to MPEG4 (AVI/MOV/MP4/MP3/3GP) file online. Comes with Desktop version to.

4. Vidtomp3.com/ Instantly download to mp3, but you must wait a little till it converts it.
