Video Attributes wrongly authored by ifoedit?

Hello,

i tried ifoedit 0.9.5 to author a DVD with one of my home
videos (PAL, 25fps, 720x576, 4:3) encoded with TMPG.
The process worked fine.

Then I watched the DVD with PowerDVD and saw that the
movie has an incorrect aspect ratio (about 720x480).
Also the screenshot function of PowerDVD gives pictures
of size 640x480.

So I tried a rip of a commercial PAL 4:3 DVD and PowerDVD
showed the correct aspect ratio and screenshots are 768x576.

Confusing for me. So I compared the IFO files of the two
DVDs. I discovered that ifoedit sets the video
attributes in all the ifo files to 0x5320 and this value
is 0x5300 on the commercial DVD.

After setting all video atribute paramters to 0x5300, my
DVD worked perfect with PowerDVD.

All souces I've found on the web state this bit in the
video attributes as unknown. Any ideas?

Maybe some problems with standalone players can be solved
by setting this bit to zero.


Regards,
Peter
