;code is not well-commented, sorry about that, I'll try to comment it nice and well, but can't make any
;promises, Also, this code writes directly into the video memory instead of int 21H (21H is slow) except

;and next time someone tells you to not use goto, ask them to code in assembly without goto... :P

    Back when I wanted to download some online lectures from MIT, I couldn't find anything that can mass download
    youtube playlists save for some softwares. I didn't want to download and install any software and such and hence
    I had to create this script (Now, I use ByTubeD to do the same in firefox).

    Extract videos from your favorite playlist. Enter the playlist id for example, in the playlist
    http://www.youtube.com/playlist?list=PLE7DDD91010BC51F8 the playlist id is PLE7DDD91010BC51F8.
    The script will generate downloadable scripts in your desired formats and prompt you for a location to save your files to.
    Please note that youtube keeps on changing their protocols so if you are using this script in say 2013
    or such, then good luck!!! And yes, if this code causes ANY problems with your pcs like for example say your
