hey love .. i think u don't have plugins in your browser like FLash player or VLc player .. thats why the sites are asking you to save and run various programs.
All the links in there can be used for watching and you can use Internet Download manager for downloading them .. some are even having direct download options just tick off Downloading through the Site's IDM as you will need to download it for no reason
i suggest Use NOVAMOV for watching and download a good version of Internet download manager and u can download it too ...It's fast and easy !!! if u need help pm me .. we can go through step by step!!
