Please suggest me some good software for editing HD videos (1920x1080, 25 fps). Also let me know the minimum configuration of the machine that will enable smooth play of HD videos. I tried to play a HD video of the above configuration on one of my machine (Machine - P4, 3 GHz, 2 GB RAM, HD 7200 rpm, Win XP) the video is very choppy and Jerky. Probably I should require higher RAM, please suggest.

Thank you in advance.
