Premiere Pro :: High Pitch Noise In CS4 And CS5.5

I recently tried Premiere Pro CS5.5 and CS4 (trial version) to replace my Corel Video Studio X6 which tried to replace Windows Movie Maker. Video Studio and Movie Maker both crash whenever I imported large video files.
 
Anyway I'm getting a problem where the video files I import to Premiere Pro CS4 and CS5.5 have a high pitch noise in the video preview.
 
It's a high pitch noise almost like it's getting feedback from something. Also when someone is supposed to be talking there's a very low distortion, like the audio started playing in very slow motion but the high pitch noise is still present.
 
I'll put a link at the end with the video file that's giving me trouble.
 
The video and audio are in a single AVI file. The video format is H264 shot at 60fps and the audio should be Mpeg-1 L2, 48khz at 320kbps. I don't know if the video's audio is in 24bit or 16bit.
 
I've tried different settings for premiere. Trying 60fps and 30fps for the framerate for the project. Trying 44khz and 32khz and 96khz didn't fix it. Using the "Desktop" preset in CS4 and Custom for CS5.5.
 
My audio hardware is a Logitech G930. It's a wireless USB headset with microphone. My motherboard audio is Realtek HD Audio. Both are enabled but I only use the headset now and nothing is being sent to the Realtek audio chip (according to Windows' sound options). The headset plays audio at 16bit 48khz.
 
The video file plays fine in every media program I own that can play the h264 codec. With the exception of Movie Maker and Video Studio x6. Video Studio will preview the video and audio just fine but when I try and skip around the program hangs and crashes. Movie Maker just plain crashes when I try and import the video. Some of the programs that can play the video are VLC, Media Player 11, and Media Player Classic.
 
I'm not sure if Final Cut Pro has the same problem. I don't have a Mac so I can't test it.
 
Here's a sample video that works the way it should. I pulled a BIK file from a game and converted it to H264 in AVI. Not sure what it's audio format is.

Here's an afflicted file. Not the exact specific file I have been talking about, but it has the same codecs. This one is shorter in length and smaller in size. It still has the high pitch noise, but since there is no one talking in this you don't hear the weird low pitch distortions.
