VideoStudio :: Camera Captured Video - Audio Stutter

I use two cameras to capture video. I have been using my Sony DCR-SR47 Almost since the day I bought VSX3. I am still using both. However I am now having stuttering in the audio. I do not have to render the video. I can import the video and play a clip fine, once I trim it then do a playback without rendering it I get the stutter. It occurs at regular intervals.

Here is an example [URL]..........

The audio is also giving me a "reverb" effect. Like a barrel effect. This is the input format of the footage. This is the output footage

Here is another example, here I converted to AVI, yet same effect. [URL].......

Output: Using Windows XPSP3 with all current updates. And have all codex installed. I did switch from using CCCP codex package to K-Lite recently.
