Hi,
its simple so just follow the requests traffic of the site so then you can also find the video source to download the video directly.First it calls a settings url with your video link as referer and as answer you get the storelocation address of all video versions of this one video (SD / HD etc).After this comes the playlist stuff to split the video in parts.So to make it simple you can do this...
Code:
http://www.jacquieetmicheltv.net/videos/show/123/any_video_name.html
http://www.jacquieetmicheltv.net/api/video/123/getsettingsurl/
...just enter the value in the path of your video and call the settingsurl link then you get all video links of this video.
