I have a WD 200GB disk I use for capturing video from my DVi camera. I capture 1 tape (60min) in one file approx. 13GB in .avi format. I have about 60% of the disk filled and defragmented, scanned for bad sectores etc.. When playing back a file - CPU goes to 100% and video doesn't play smothly at all (stops and starts all the time). Tried Windows Media Player, RealOne and Adobe Premier. Other files around 600-900 MB works fine when playing. I have a Dell Dimension 8300, P4 3GHz, 60GB (C), 200GB (D) film drive), 40GB (F), 512MB memory, 128MB DDR ATI Radeon 9800. Does anyone have any good suggestions?
