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.

ASFRecorder does not support RealMedia or QuickTime. ASFRecorder only features HTTP streaming in WindowsMedia format (ASF). ASFRecorder does not (and will never) implement Microsoft's MMS streaming protocol. For this reason, you might encounter some ASF streams that cannot be recorded with ASFRecorder.

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.

(*) IMPORTANT NOTE: The fact that you can now technically do this does not mean that I want to encourage you to do so. Creating unauthorized copies of copyrighted material is illegal.

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 does 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. So far, however, the industry has almost completely ignored the need for using Microsoft's Digital Rights Management solution.

Can the server determine that I am using ASFRecorder?

ASFRecorder imitates the HTTP protocol used by 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

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.
