    Hi I'm having a little problem. I use avi2dvd and I was sure that it was working perfectly but then I realized that my pal dvd's are ntsc =(. I'm from argentina so when I make my dvd's in this program I choose "NTSC to PAL" option. I play my dvd's in my computer so I haven't noticed it was not pal until I tryied to play it in friend's dvdplayer and it showed something like "FORMAT NOT COMPATIBLE WITH TV"
    The thing is that I used Nero info tool to check the dvd and it showed:
    - Format: NTSC
    BUT I used avicodec to check the fps (PAL = 25 fps) and it shows that the vob files from the dvd are in 25 fps.
    So I'm lost. If the dvd is in 25 fps why is it still NTSC??
    Can somebody tell me why is this happening?

    Thanks a lot. Mary.

    I'm not sure, bacause I never used AVI2SVCD, but I heard it uses, as encoder, CCE, which has a similar problem: the output movie is as like the input one (e.g. 720x480 29.97 fps [NTSC] when you would want to make a 720x576 25 fps [PAL] movie [the same for different formats]).

    For instance, you could have made a 25 fps movie, but if its resolution is 720x480 instead of 720x576 , it is no a PAL compliant movie.

    You have to do a couple of tricks.
    For instance, let's suppose you start from a 640x360 29.97 fps AVI movie and let's supose you have no application which changes the framerete for you (even if it seems you have it, but I never used AVI2DVD).

    [bold]First, you have to change the resolution[/bold].
    CCE (and, I suppose, AVI2DVD too) doesn't resize the movie, so you must do the resizing for the encoder, before encoding it.
    1) Open the AVI with VirtualDub
    2) Choose Video___Filters___Add and add the Resize filter.
    When you must set the filter, choose New width: 720, New heigth: 576 , Filter Mode: Lanczos3 (the best one).
    After you've done this, do File___Start Frameserver (let's hope you installed it. Otherwise, click on auxsetup.exe and install handler).
    Call the framserving file, say, movie.vdr.
    Do not exit VirtualDub. Keep it in the taskbar.
    Now, load movie.vdr instead of movie.avi. The output M2V now will be a 720x576 movie (I'm using PAL DVD specifications. This method can be applied in all other cases).
    We now are very close to the end. Let's suppose we have a 720x576 movie which is close to PAL specification, but has a framerate of 29.97 instead of 25.
    [bold] Second: you have to set correctly the framerate of the movie[/bold].
    Download neuron2's DGPulldown from http://neuron2.net/dgpulldown/dgpulldown.html , run it, set
    Custom: 29.97 --> 25. Click convert.
    In few minutes you have a movie.pulldown.mpv file which is fuly compliant to PAL specification (and has A/V in sync, once muxed to the sound file, if the original movie would be).
    OK?
