I am trying to edit a dvd and I converted the .vob to a 720x480 dv-avi. The new dv-avi has almost perfect play back in VLC Player but when I export it into a project in Premiere it becomes really choppy. I have a 1.2 gig Athlon with 1 gig memory. Is my computer capable of doing this? Should I be using a different file format for editing? I am totally new to this so don't rule out the obvious.
