    Hi, i've been trying to convert a h264 file(wich has 23.9 fps) to NTSC dvd format(m2p) with Canopus Procoder 3, but with no sucess.

    In the convertion process, about 1 minute after the conversion start,a message appears saying "h264 decoding error".

    So my two main questions are:

    How can i convert the 23.9 fps h264 file into a dvd NTSC 29,7 file with no quality loss?

    or

    How can i fix the "h264 deconding error" ?

    Thanks in advance

    I'm not an expert on h264, but one of the ways I've addressed
    issues like this is to use Yamb to extract the streams, then
    MKV Merge GUI to create an MKV out of these extracted files.

    Install Avisynth and create a simple script like so:
    DirectShowSource("c:\my_file.mkv",fps=29.97) << (fps should match src).

    Then open this script in the Canopus encoder.

    Regarding the frame rate, it's the normal thing when 24fps movies
    are played back at 30fps (NTSC TV). The frames are flagged and some
    repeated during playback. It's called pulldown. Usually, the encoder
    handles this, but you should check the settings.
