Hey, I would like to know why my PC can't play videos no more. I've installed the following codec(s) packs: 1:Theorica Divx Video Codecs 5.0 2:Xvid-1.1.3-28062007 Final Release. 3:AC3Filter 1.1.3 4:Storm Codec 7.02.01 I use the following media players: 1:Windows Media Player 11(default). 2:Jet Audio Basic 6.2.4 3:Nero Home Essentials SE. 4:Media Player Classic 22.214.171.124 When I try playing any clip,be they AVI,DAT,MPEG,ASF,3GP,MP5,RMVB,MPE or whatever, the CPU usage suddenly shoots up to 100% with the application that's trying to play the clip eating up ninety- something of the CPU. My PC is a crappy Compaq EVO D510 SFF PC with 2.0ghz, 1024MB RAM, Windows XP Proffesional SP2, 64 MB nVidia GeForce4 MX420 video card. By the way, I could watch clips on my PC before installing Storm Codec. However, after I installed it everything went kaput. I've tried uninstalling it but doing so cleans my system of all the codecs (even those for MP3s)! Can anyone please tell me what to do or what to download? Thanks in advance.
