Audio drifting within Premiere

I've recently been trying to deal with this issue and I'm totally lost. Scouring the internet hasn't brought about resolution. I've been capturing gameplay footage using a Roxio Game Capture HD Pro and using Premiere Pro CS6 to edit it. Sometimes I run into an issue where, after importing my footage into Premiere, the audio drifts in and out of sync from the video (not a constant rate). Sometimes it will be in sync in places, other times it will be several seconds off. The length of the audio and video are the same. The only way I've been dealing with this is to constantly trim and move sections of audio around when I notice the drift, but this creates gaps in the sound, or sections where two sections of audio overlap from trimming/moving to maintain sync. It's not at all a sustainable work-around.

 

The part that's really confusing me is that this is only happening when I'm playing the footage in Premiere. When I open the source footage in any media player the sync is fine all the way through.

 

Details from one of the clips I've been having issues with:

 

2.03gb

length: 20:45

1920x1080

data rate: 14063kbps

total bitrate 14072kbps

29 fps

---

audio

bit rate: 9kbps

stereo

48 kHz

 

.m2ts avchd, h264 codec

 

Sequence settings are the same in Premiere.

 

Anyone have any solutions?

    >Bit rate mode : Variable

     

    This is NOT about your process, but it does talk about Premiere (can't remember if this is about Pro or Elements) not editing variable bit rate files

     

    Iphone won't edit easily because it uses a variable frame rate - A fix in message #22 http://forums.adobe.com/thread/934466

     

    I will GUESS that you have the same problem
