videocapture and videoeditingDon`t forget about differenses in perfomance of desktop and laptop harddrives. Harddrive is bottleneck in videoditing. For capture digital video it will be enough 4200rpm dma66 even dma33. However if you planning EDITING your video using some sophisticated video editors even 4500 udma100 ata5 will made you crazy (I mean Ulead Media Studio pro 6.5 or Adobe Premiere 6). But for Ulead Video Studio (Media and Video is BIG differences)it will be enough, but barely enough. The best decision IMHO is external fireware or usb2.0 7200rpm-desctop or even though 5400rpm-laptop harddrive. Using 2 harddrives you can configure it for record data to fastest drive and write from another (slowest). This is the simpliest and most affordable way to achieve increasing perfomance.
And the best way use Google for "videoediting".
