This is my first post here. If the post is in the wrong place, please point me in the right direction.
I recently bought Nero 7 Premium. It mostly works fine and the end DVDs work perfectly well in my home player.
My big problem is what I can see when I am editing the video on my PC. The playback is appalling, really jerky and almost unusable. Often, the picture freezes while the sound carries on. This makes it very difficult to watch and to edit.
I have a Pentium 4 1.9GHz processor and 1GB of RAM. I have not had these problems while working with trial versions of Adobe Premier, Ulead, Pinnacle or indeed MWMM.

Can anyone help?
