Can you watch your favorite youtube videos on you ipod touch without connecting to th

I was wondering if you can save your favorite videos from youtube and watch it later in the metro (subway) or in an airplane where theres no connection.Tnx.

Yes, of course you you can.. ^_^
First you need to download and convert the video from youtube to mp4 format or avi format.
Then after a successful download and convertion you can burn the video to a dvd or you can save it in your USB device.
Now you are ready to watch the video even without internet connection. ^_^
