    Sync Problems when captureing Video can be caused from a number of Different things...

    Dropped Frames while Captureing can cause sync Problems...
    Dropped Frames are usually Caused from either your Hard Drive not being Fast enough to Write the Video data to the Drive in Real time Or it can be caused from your CPU being too slow to Compress the Video in Real Time....

    Another thing that Can cause Sync problems is the Latency between the Time Clocks on your Video Capture card and your Sound Card...This Latency is usually only about a second or two per hour but over a whole movie it can cause a Pretty Major Sync problem....

    Good Capture Software Should Compensate for this Time Latency and for Dropped Frames....Maybe Try Captureing directly to Mpeg-2 useing "InterVideo WinDVR 3.0" as it can compensate for Dropped Frames and the Latency between your Sound and Capture cards and it will also Save you a Bunch of Time you would spend encodeing to Mpeg-2 from AVI.....

    Cheers

    PS: If you want to capture to AVI look for a Setting in your Capture software that is called the "Master Stream" setting and set it to "Video" and this should Make the capture software Properly Compensate for Dropped Frames and any Latency....
