    Hi Guys.... Having a weird problem.

    Just finished burning an AVI to DVD using <AVI2DVD> and then burning the ISO to DVD with <DVD Decrypter> followed all the steps and everything worked fine....


    Just 1 problem... when I play the dvd the video and audio are synced but slow.... Not slow as in Very slow... but slow as in all the women sound like men and the men sound like they are on Vallium..

    any clues?


    Regards

    The video was encoded at 29.97fps and is actually a 23.976fps video (or a PAL 25fps video), and pulldown was not applied.

    OK sounds like it makes sense....

    But Im Having a Blonde moment...

    the original was a NSTC AVI with 29.97FPS...

    the output was sposed to be a PAL ISO for dvd...

    where,what or who do I pull down?

    forgive me for being plank like....< flutters eye lashes >

    Regards

    I was guessing at the framerates, and had no idea you were doing an NTSC to PAL conversion.
    You have slowed down the video to 25fps, and slowed down the audio at the same time.

    First, encode as NTSC, burn a test to DVDRW and see if it plays. About 90% of players will do it, and output the correct PAL signal for your TV set.
    If so, you need not do any conversion.

    Second, if conversion is needed, avi2dvd may not handle the audio properly, and not be the best software for the job.
    Any time you attempt a conversion like this, there can be troubles, and the best solution is to not convert at all.
    If necessary, re-encode video to PAL 720x576, letterboxing if necessary. Keep the file at 29.97fps though.
    Demux the audio and video to elementary streams.
    Load the video into DGPulldown, and tick the 29.97 -> 25 fps box.
    Author the dgpulldown.m2v with the previously demuxed audio.
