The minimum requirement for HDV without using Cineform products is listed as 3.4GHz and 2GB RAM. It is possible to get Premiere Pro to use up to 3GB with a switch but that is really only of value when you have 4GB not 3GB. Remember that Windows takes much of 1GB anyway, and you will often want to open AE or Photoshop even if only temporarily.
The best way to make a system HDV friendly without Cineform is to get a dual core processor, or two processors.
Since I am Cineform’s biggest fan, I am amused at the lengths that people will go to avoid getting better quality and faster editing speeds.
