I am using mozilla firefox. At tools, click Add-ons, then left page Extensions, look for Video Downloader Professional and installed. I think you have to restart firefox to apply the changes. Then top right of firefox browser it's an icon, near Menu. When you go to dramacool, for example, you open that movie or episode from the series you wanna download, play it then in that corner that icon will become a green arrow, click on it. it will show an small window download this video in flv or mp4. Depends some time. It will save it in one of your computer folders.
Firefox has lots of downloader apps.
Hope it works.
