[C#] YouTube Downloader

One month ago I initially started with this project, but after YouTube changed something in the way they retrieve the stream of the video, my approach no longer worked.
I requested help here, and after a while I figured out how it worked (Thanks to sunnyboy184).

How it works

1. Fetches the YouTube video HTML
2. Parses it and grabs the different qualities
3. Displays the video quality options to the user
4. Allows the user to download either the video or the audio
5. Outputs the file in a download folder or:
6. Extract the audio from the downloaded file using FFMPEG

Extra features

• Able to process new 'youtu.be' URLs
• Displays download progress
• Automatic existent file renaming
• Open containing folder after download
• Supports simultaneous downloading (New in 2.0)

Changelog
1.0 (Initial release)

2.0 (First update)

• GUI redone (no seperate download form. More compact and clear)
• Different quality selection
• Able to download both audio and video
• Added an extra form to download the FFMPEG program (opened by simply checking 'Audio')
• Queued downloading
• Simultaneous downloading (maximum up to 5)
• Video information shown
• Download progress display differently
• Removed possibility to play videos afterwards
  
  Others:
• The source is now (almost) fully documented

2.0.1

• Fixed a minor mistake in duplicate entries
• Fixed error where you could still shift around downloads while downloading

Planned features

• Once a video is added to the queue, attempt to retrieve the Video title to make the queue more user friendly
• Possibility to change quality and audio/video of videos already added to the queue

Requirements
Microsoft .NET Framework 4.0 (Link)
You can also change the target Framework and apply some minor edits to the source.

Remarks
This is program is relying on the structure of YouTube pages. If this will change, the program will most likely break (unless it's only a minor edit)

Feedback is very welcome.

If any glitch or bug is found, please tell me!

What's the Password of the rar folder?

Should be added to the main post now. Stupid mistake...

It really helped to look how other programs grabbed the signature for requesting the video, thanks :P

It will be nice if the program could support multiple downloads at once.
Like maybe make a lists of all concurrent downloads and their progresses (maybe a progressBar and an E.T.A status on each line).
Also, it will be great if you could make a notifyIcon in the taskbar and hookup a quick shortcut to download a video, so that the main form doesn't have to stay open at all times.

But nonetheless, very nicely done :D

He released the source. Learn C# and do it yourself.

He also did say "Feedback and is very welcome." (On the last line of his original post if you couldnt see),
Read the details before accusing me of not being able to code in C# man. It aint cool. :D

Hello Gravious,
I can tell you that the program you've just made is near industrial level. However, i feel that simultaneous downloads are a key feature and should be implemented. Opening instances after instances of the downloaded really is a pain.
Nice job nonetheless.

I'll start on this and add it as soon as I'm finished ;)

Nice little program here, I find it nice how below the input URL text field, once the URL is pasted it shows the video title.
Good job on this man. +1 +like.

Good job on it bro. It'll get around.
