So my video capturing has gone well. I have a K-World USB DVD Video Capture Device, and it captured audio great...until today.
I use U-Lead DVD Movie Factory and Windows Movie Maker.

Anyways, so usually I capture video, and the audio is crystal clear.
Today though, I tried doing it (I remember earlier this morning I had to restart my computer because I accidently ended a process in the task manager--maybe that's why this problem arose) so after I restarted my computer and proceeded to trying to capture video, the audio captured, but if it came to a loud part, it would go loud and fuzzy, and it was overall clear and undistorted.

I have SoundMAX Integrated Digital Audio, and the audio input goes in my Line In to the sound card.

What do I do? I need this problem fixed today for something I'm working on.
Thanks.
