I have a fresh install of Windows XP and every video I play is a blank screen with sound. I figured I was missing the right video codecs and downloaded the nimo codec pack, didn't help. Then I unistalled those and downloaded vlc media player, didn't help. I went and hand deleted all my video codecs under Control Panel > Sound and Audio devices. Then I installed Ace Mega Codecs pack, still getting a black screen and sound with every file I play (besides .rm and .mov which I play in realplayer and quicktime) Any ideas on how to fix this? I'm out of ideas, thank in advance.
