I'm editing on a dell Presicion 650 dual 2G (533 FSB Hyperthreading: ON) Xeon, 1 GIG (dual channel) ddr RAM, U320 scsi system drive, RAID 0 for media. I'm importing the new HDV format .m2t files into the project set at widescreen DV specs. To preview from the clips I have no issues, but if I play from the time line it drops to 10 fps. At best I get 18-20 fps when playing the m2t file with a smaller preview window (preview auto, docked at the bottom). Before I had the raid and scsi, the frame rates were much lower (9-10 fps) do I need FASTER drives yet? How?

Is there anyway to enhance this? Or am I just stuck, whats my bottleneck? Why does the clip preview ply fine but not on the timeline?
