Youtube is not a reliable place to watch video.Some video are slow to watch in HQ or HD at some hour of the day.The best way is to downlload it to you hardisk.This is expecialy true for the HD content, becouse not all computer are fast enough to watch it online with the FlashPlayer.
Which program to use to download Youtube video?
How this programe work. Via Youtube server it is posible to get upto 999 video files from one user. All the video from that Youtube user are visualise in one alfalbetical list. And can be selected to be download.
I have tested on XP with SP2/SP3 and vista.
After you download the all the mp4 files you can watch it with VLC media player. Place it in the playlist for easy watching it as one part! In de menu Playlist,Show playlist, add directory. It is also posible to save the playlist for later resused.
It is also posible to burn the mp4 files to DVD. So you can watch it on your TV. Use the free version like http://www.dvdflick.net/
The HQ version is Ipod and IPhone compatable. For other player you must convert it with free http://mediacoder.sourceforge.net/
Known issues:
It may take upto 2 day after YouTube video release that the file will be shown in the list.(YouTube limitation)
When downloading is in progress and the program is closed, then the present incompleate video file is not deleted as it should be.
