Audio Sync problem when converting mpeg2 to avi...

    Hi Everyone,

    I recently bought a little USB TV Receiver with a view to using it record my
    favourite TV shows and archiving them onto DVD's. I'm hoping to be able to
    re-encode the captures into avi (DivX) format, so that I can then watch them
    on my Standalone DVD that supports that format. The intention was to get as
    much as possible onto the DVD's, hence my preference of DivX/XviD.

    Now, the DigitalTV decoder only appears to have very limited options as far
    capturing goes and I can only save captured video as Mpeg2. The quality of
    these captures is excellent and I'm very happy with them, however, when it
    comes to converting to avi I seem to be having some problems.

    The mpeg2's are quite large files, just under 2Gb for an hour of video and
    when I convert them to DivX format, using DrDivX, the file size is reduced
    to around 600mb which is still quite a lot for an hour's video but I like to
    keep the image quality as high as possible. Here's where the problem comes
    in; the conversion looks and sounds great, but at about 5/6th's of the way
    through there is a dramatic loss of audio sync. It goes out by at least 3
    seconds, which is unacceptable.

    I've tried changing various settings under the DrDivX options and
    re-encoding but it makes no difference. I have also tried encoding direct
    to DVD using Nero and the same thing happens. I've also tried converting to
    XviD with AutoGordianKnot and it fails to convert.

    I wonder, is this a common problem encountered when trying to convert from
    an mpeg2 file? Can anybody recommend any other software that I could try?

    Any ideas much appreciated :)

    By the way, the TV Box is one of these:

    Many thanks for the advice, Mark. I've just finished re-encoding the file
    to AVI and it worked perfectly and even knocked another 100mb off the
    finished file :)

    Vince:

    Glad to hear it. I assume that you used VideoRedo on it?

    Cheers...

    I did indeed, Mark.

    It's an excellent little program and I'll definitely be buying a full key
    for it when the trial is up. I'm just getting to grips with removing some
    ad's in a programme that I recorded tonight and it's looking like it's very
    user friendly. I can see this getting a lot of use :)

    Thanks for your help.
