Amarec inserting frames whenever I capture with audio.

[ENunn]

I'm trying to capture some gameplay and for some reason Amarec is inserting frames 40 sec-1 min into recording. Using the Elgato HD60s.

If I don't use the audio device it doesn't do this. Don't know why.

Tried changing encoding settings, rebooting, hotplugging the capture card, restarting Amarec, not sure what to do. I did try Virtualdub and the audio gets out of sync when I capture.

I've haven't had this issue until now. Not sure what to do. Any help? Thanks!

EDIT: Only seems to happen (as of right now) whenever I record at 1280x960. 1920x1080 works fine but I'd rather record in the native resolution of what the Elgato is seeing (1280x960).
