Agreed. Use another hard drive preferrebly on the 2nd ide channel (you might have to swap CD drives or something).
I'm editing video with one hard drive but my problem is RAM. I have 512mb and when playing with a long video, it quickly tops out and uses the swap file. And THAT can be a problem as well. Go cntrl-alt-delete and look at your task mgr. If you're going over your physical limit, you're bogging down the PC. I suggest at least a gig of ram for video editing. Also, get good ram like Mushkin HP, Kingston HyperX or Corsair XMS.
I am using Windows Movie Maker. I am not dropping frames. Playback on my computer and a DVD that I burned, is grainier (slightly blurry) Not a good digital quality picture.
I'm no expert .. but .. the one time that I tried
Window's Movie Media software, it would render to
CD (not DVD quality) video, which is very poor
(but it renders really quickly!)
I've tried the movie making software bundled
with my Sony video camera with the same results.
I have been using Pinnacle Studio which one can
render to fairly high quality DVD.
