When I am playing a video on youtube the audio on it plays fine. But then when I have the same video on my computer it plays all crackly and staticy. I tried to get a new driver for it then the videos started to playback fast. So then I removed the audio driver and kept the one that installs by default. I removed the K-lite Mega Codec pack and the sound played back fine but there was no video. So then I used codecfixer and it still didn't do anything. I don't know what else to do other than post something here and hope that someone knows how to fix the issue. The computer has Windows XP Professional SP3 1.3GHz Pentium 4 256MBs RAM and a GeForce 6200 graphics card. I have the latest Graphics card driver installed directly from nvidia and I have the latest K-Lite Mega Codec Pack installed. If you need further information just let me know and I will try to find what you need.
