This is the page where is the video http://www.icourses.cn/jpk/viewCharacterDetail.action?courseId=2367&sectionId=9474, I have tried to save the video from the above page, but failed.
I notice that the video url is http://www.icourses.cn/jpk/getResPlayInfo.action?uuid=53190, then you will get a combined url like this http://media1.icourses.cn:8080/process4/campus/processres/flv/2012/12/2/ff808081-3b56689f-013b-59f30c27-0050.flv, but the webserver returns a 403 error for me.
As I use the software webvideocap, it can only save size of 15MB videos, and then it will not continue.
So, will any guys tell me a better way to solve this problem and save the video?

Well, I have tried your method, but it doesn't work, it only return a 404 error. Thank you for your answer. Would you provide me a better way to achieve the goal?

I use IDM:

Well, I have tried IDM, but it can only save a part of the video of 15MB, when the saved file is larger than 15MB, the downloading is stopped.
As in the image you paste, you have download 52MB, how could you did it? Is it something wrong with my IDM configuration?

When I am searching, I find a post by you about the same question, it is here http://stream-recorder.com/forum/cant-download-icourses-edu-cn-t15323.html, did you solved the problem finally?

IDM would be better, but if it fails you try this (http://www.mplaze.com/streamcap/). It works like much like webvideocap.

Start stream hunter, play video in browser.

Video will show downloading in "now saving" section of stream hunter, but this will only download 15MB. However, right click file that is downloading and choose "download it", and the whole file will download. You can stop the video playing in the browser after you choose "download it".

I have tried it for several times, and it still failed downloading when the video is larger than 15MB. I don't know how to paste a image here. It seems that the web server has some technical means to prevent downloading.

Other options;

Each 15MB segment will be saved in browser cache, copy each one out before the next one starts and join them. Each prior segment will be deleted when the next one starts.

Let entire video play in broswer and stream hunter will save several 15MB segments that can be joined.

Get IDM with "special key" setting working.

I tried "Flash Stream Hunter", following the steps that you mentioned above, but downloading stopped at the 15MB point if you don't close it manually. Here is the result:

If the web server only transport each 15MB segment once a time, and each prior segment will be deleted, how can I copy each one out?
Although it seems possible in theory, which tools can I use? Or how to get the point when each prior segment is deleted and the next starts?

You can complete the download with several different utilities if you pause/stop and then resume/start it again, every 15MB.

I noticed this with Free Download Manager, and TubeDigger.

For example, in TubeDigger, go to video page but then quickly leave it as soon as you see download link (don't let video play long). Then you can download it. When it stops at 15MB, stop and restart the download, and then again every 15MB. Don't use rec mode as it results in separate files.

For Free Download Manager, get link to video (I used chrome extension) and paste it in FDM. Then you just have to pause/start it every 15MB.
