What is ASFRecorder?

ASFRecorder is a tool to download and store WindowsMedia streaming content to your hard drive. The resulting files can be viewed as often as you wish. The files can also be copied without any physical restriction.

The program is written in portable ANSI-C! Use it on SUN, Linux, Windows. HP-UX and MAC ports should be easy. The graphical user interface works on Windows only.

For more details, have a look into the README file.

What can you do using ASFRecorder?

Download music videos, movie trailers, audio clips or complete songs. You can download the high-quality (high-bandwidth) version (often 300kbit/sec) with slow modems. You can also record live-broadcasts (e.g. concerts, TV shows). You can then copy and spread the downloaded content using Napster, GNUTella, FTP, IRC or whatever.

High bandwidth movie trailers usually are 3-6 MB in size. High bandwidth music video clips are usually 6-12 MB in size.

Why is this possible?

It is possible because content providers seem not to be worried about the safety and copy-protection of their content. They trust in a proprietary streaming protocol invented by Microsoft and they completely ignore the need for activating any security options that this protocol would indeed offer.

What is the outcome of all this?

The result of all this might be that some content providers will have to shut down their service - or at least temporarily disable a part of their service until they or Microsoft come up with a fix or protection against unwanted downloads.

Can the server determine that I am using ASFRecorder?

Currently not. ASFRecorder imitates the protocols of a Windows Media Player. The server will not notice any difference wheter you are watching the content with ASFRecorder or with Windows Media Player.

Legal Issues

(excerpt from README.TXT)

Q: So is it legal to download and distribute this tool?

A: Yes. This  is a very simple tool using a very simple internet protocol. It
   does  NOT  break any encryption or authentification procedure.  So I don't
   see any point why this program could be illegal. Download, copy and spread
   as you like, THIS PROGRAM AND ITS SOURCE CODE IS LEGAL.

Q: Is it legal to use this tool?

A: That depends on what content you actually download with this tool.  If it
   is copyrighted content and if the download is expressly prohibited by the
   content provider, you are acting in an illegal manner.

Mirrors and support needed - Quickly!

I need people to spread this program quickly. I need people who want to support this program and set up download pages similar to this. If you don't want to spread the program, then please spread the word.

Why that? Well, I am sure that some companies will try to stop distribution of this program because they don't like it. And that's why this program needs all the third-party support it can get.

When redistributing this program, please don't remove the source code. Please don't infect the distribution archive with viruses. And please don't claim that you or your "c00l eLiTe HaCkEr GrOuP" has written this program. Thank you.

WWW-Providers, please read this

Please do not remove this page because of any _potential_ trouble with Microsoft or content providers. I can understand when you react as soon as you are contacted by these companies, threatened with legal action. But don't remove this content by "obedience in advance", as this would be sort of cowardish.

In certain European countries, for example, there are no patents on Software and file formats, like in the US. Therefore it is not possible that Microsoft could claim a violation of their patents in these countries.

This program is neither based on secret or undisclosed Microsoft information, nor on the US-Patent of ASF. For understanding the streaming protocol it only took some few hours of "concentrated examination" of the data stream.

The consequences of this unsafe implementation will now truly worry the streaming media industry (who now get a huge piracy problem) and Microsoft (who might get bad headlines).

Enough talkin'...
