MIT Open Course is very famous, I do not introduce here, go straight to the theme
Landing at MIT's homepage http://mit.edu/
Go to the Public lesson video page
I'm here Wednesday, December, http://mit.edu/'s page screenshot

Select video
Education
Courses, OpenCourseWare, video

Enter the page is
http://mitworld.mit.edu/

Click on Play now to start the Realplay playback video. can also be in Search now. , found in selected Categories and Hosts. But in fact, the public video is relatively few, I suggest that you directly point to see all the course list.

In the course list, it is recommended to point to the MIT HOST to sort the courses according to the relevant disciplines. Then you can look for it on a page. More than 10 pages, turned over, it seems that MIT still need to put some more video lessons in order to meet our thirst (hunger) of the need for knowledge ah. V ^_^ y

Now say the key question, how to download the video file to the local hard drive. I chose a course.
The Mystery of Light
July, 10:00 AM
MIT Kavli Institute for Astrophysics and space

Although not to learn this professional, but the universe, the sky, is always fascinating ...

Enter this course page http://mitworld.mit.edu/video/291/
Click Play Now to enter the video playback page http://mitworld.mit.edu/video/289/
The default is the Modem 56k, but we download to this machine do not consider the problem of delay, so simply choose the clearest broadband 220k then play Now
This time is the real play, call the Realplay program to start playing. But the general speed is very slow, and can hardly play smoothly. Of course, if your video is extremely fluid and you don't want to save it, it's a good idea.
Press Ctrl+i to see the playback file information in the Realplay Player, or select menu action file > Clip Properties > View clip Information

Where the filename is the download address of the video. It should be a. ram file. The address of this course is
Http://mfile.akamai.com/12800/rm/mitworld.download.akamai.com/12800/mitw-chandra-astro-lewin-light-04jul2005-220k.ram
Select, CTRL + C to copy this URL
Start the network drive belt and press INS to add a new task (this time realplay can be closed)

and then download.
Will find the download is soon over. But just a small file of 331 bytes. If played with Realplay, it will still be linked to the network.
Locate the file on your hard disk and open it in Notepad, which is the Notepad that Windows comes with.

You'll find this is a text file, where the first line is the real download address for this video.
rtsp://a294.v128001.c12800.g.vr.akamaistream.net/ondemand/7/294/12800/v0001/mitworld.download.akamai.com/12800 /mitw-chandra-astro-lewin-light-04jul2005-220k.rm
OK, check this address, Ctrl+c,alt+tab switch back to the network belt, press Insert to create a new task, pop-up window directory to choose a larger place to store, because this video course has 151MB, the number of blocks recommended 1, that is, download the number of threads, a lot of useless. Finally press OK (O) to start the download
I can open the speed here, showing the download speed around 24k.

Well, I wish you all a successful download.
