    I've captured a vhs tape using Leadtek's Winfast tv2000xp expert capture application. I then used Leadfast to render the saved vhs file and burnt it to a dvd disc using the DVD MovieFactory 3 SE application that came with this software. When I play the DVD back the audio is not in "sync" with the video.
    Something else to: While capturing the vhs tape I noticed what looks like a "tracking issue" - at the bottom of the video - I used the Hitachi UX6450 (good quality) VCR remote to manually and automatically adjust the tracking - but I couldn't get rid of that little bit of "shaking" at the bottom of the picture while capturing the video. This "shaking" also showed up in the DVD.

    Does anyone know how I can solve these two problems?
    1) the out-of-sync video/audio
    2) the "shaking" (looks like when you have a traking problem) at the bottom of the screen while capturing vhs video.

    Cheers,

    Your audio sync issue may be a result of dropped frames in your video capture, the only recommendation I can make to attempt to solve that, would be to "capture" the vhs twice. The first time capture ONLY the video, then replay the whole thing, capturing only the audio, then recombine the video with the audio AFTER encoding the video to mpeg format. The other option would be to capture the video and audio, but demux the files, and encode seperately then recombine. I've had this problem before, and these were the only solutions I could come up with, however it definitely sounds like a result of dropped frames. This may not be the easiest solution but it definitely will work.

    Wow - this can get time-consuming. I thought after spending $3000 on a new computer and asking around for some good advice on software and capture cards etcetera I was going to connect the vcr to my computer - open the video studio8 software and "boom" it would be easy and done without much trouble at all "NOT!"
    I'm a little discouraged here, but I do appreciate your answering my question.

    Thanks,

    GWW

    Yea, unfortunately things can get a little complex when dealing with issues like that, but you may also consider using a different encoder (I personally like tmpgenc, although it's not quick) Using most encoders you can encode the video to elementary streams (in tmpgenc labelled E.S. Video+Audio) and then use your dvd program to select the m2v as the video source and the mp2 as the audio source, and you can use that to cut out the offending section of the screen during the setup process.
