Vobsub original size error

[ERQ]

I had created a idx/sub for BRAZIL documentary(special feature) its in 4:3 A/R PAL. But after muxing it to encoded x264 video, the subs are way bit downward and subs on the edge aren't even shown. I checked the .idx file and found that the attribute
# Original frame size
size: 720x480

I knew it should be 720x576 and changed it.

Why the hell Vobsub is detecting in such manner as PAL subs as NTSC?

1 more thing after changing it to 720x576, subs are shown properly.

This sub is in PGC 3 of the IFO(VTS_03_0.IFO). I found that the IFO have(using IFOedit) Menu Attributes:MPEG-1 720x480 (NTSC) and Title Set(Movie) Attributes:MPEG-2 720x576 (PAL) . I can confirm that the DVD don't have any mpeg 1 NTSC content as menu or movie. I think vobsub is getting its size attribute from "Menu Attributes" not from "Title Set(Movie) Attributes".

Next time use IfoEdit to change the menu from NTSC to PAL. Assuming you have the DVD on the HDD.

That the menu is NTSC while the project and all files are PAL I noticed to be a problem of TMPGenc DVD Author too.
