Hi,
so thats are just direct video locations and no rtmp* streams.Just have a look into the page source in your browser and there you can find the direct video file link.
Code:
http://videos.ancdn.com//amra/trailers/mobile/amralilybillytrailer_mobile.mp4
Just download it with any download-manager or enter it into your browser but be sure that you have disabled your player plugin [VLC used to play mp4 files if you have installed].
So for this kind of videos you can also use browser Add-On tools like NetVideoHunter which can also show you the direct download-links of the video what you playing in your browser.
