Video files, mainly dat and mpeg files are skipping and playing fast in Windows Media player, Real Player, PowerDVD etc on my PC. Audio files play okay. I have uninstalled and installed my AGP card drivers, but the problem persists. My rig consist of ATHLON XP 2400+, ASUS A7N8X-DELUXE mobo, DIGITAL 512MB DDR RAM,SAMSUNG 40 GB 7200 rpm HDD,Liteon DVD ROM, RIVA TNT2 M64 AGP card (Will be upgrading to a GECUBE RADEON 9600 PRO 256MB card). OSes are WIN98SE (C drive), WIN XP PRO (D drive). Could someone pl help ? Should I reinstall Windows.
