How to sort playlist on youtube custom player

I see a lot of people having problems in sorting video playlist of their youtube custom player.

By default, without doing anything, youtube custom player will sort videos from oldest to latest but most of us wanted to sort videos from the latest to oldest.

Here is what I found to resolve this, and to do this is NOT through youtube custom player but on the video playlist.

Please see steps below.

1. Login to your youtube account.

2. Go to your video playlist - http://www.youtube.com/my_playlists

3. Change the order by changing the number of your videos by clicking the number of each videos and change it.

4. This should be done each time you added a new video, unless google was able to have this on custom player.

5. Changing the playlist order will changed custom player accordingly.
