Using DGPulldown to convert between regions

[Delta2]

Hi,

Don't know if this is the right forum

I'm using "pulldown method" to convert movies from pal to ntsc and vice-versa

I get in some players a message of "region unknown"

Does this "pulldown method" give a incompatibility issues with region locket DVD Players ?

I know how pulldown works, but I don't know how dvd players recognizes a region in a DVD, is it by FPS ?

thanks

Pulldown has nothing to do with region coding. Region coding depends on your DVD authoring software.

Thanks, is strange then, I use DVDAuthor and I force ntsc format

- <dvdauthor dest="C:\TESTES\author">
<vmgm />
- <titleset>
- <titles>
<video format="ntsc" />
<audio lang="en" />
<subpicture lang="pt" />
- <pgc>
<pre>subtitle=64;</pre>
<vob file="C:\TESTES\multiplex.mpg" chapters="00:00:00" />
</pgc>
</titles>
</titleset>
</dvdauthor>


can I make a region free with DVDAuthor XML ? or need I to use IfoEdit ?

Players will sometimes react against the resolution of the video. NTSC and PAL don't use the same resolution or framerate. Region coding in and of itself is completely separate, and I don't know that DVDAuthor does that stuff anyway. When you set 'NTSC format' it's really saying 720x480, 29.97fps*. If the video doesn't match those specs, it may fail with a region error even though a mismatch error would be more descriptive. Same thing with PAL mismatching (i.e. it says PAL but the video isn't 720x576, 25fps*).

*I'm just going with D1 by default, although other resolutions are part of DVD spec - still, though, those other resolutions have to be the NTSC or PAL variant of those standards.

If you're going with NTSC, the resolution has to be part of the NTSC standard, even if you've applied pulldown flags with DGPulldown.

DGPulldown will peoperly set the framerate to 29.97 if that is what you specify for the output frame rate.
