[dvd::rip] DVP 630/DVP 642 and Square Pixels

[Horst Tellioglu <horst@xxxxxxxxxxxx>]

Hi,

I _think_ I found out, why movies encoded with dvd::rip using XviD are not 
playing on the Philips DVDP 630/642.  The error looks like this: when trying 
to play a file the player reads the index and then skips through the video 
but never shows a picture.


I tried to use the settings as described here:

and mentioned here:

The critical setting for me was 

"aspect ratio set to SQUARE"

I don't know how to do this with dvd::rip.  An analysis of the encoded videos 
with mpeg4modifier (under Microsoft Windows) always showed 

Custom pixel shape (1:1 = 1,00000)

The custom aspect ratio "1:1" seems not to be the same as the aspect ratio 
"square".  I have no idea what this means, but changing the aspect ratio from 
custom to square with mpeg4modifier made the videos playable on my DVP 630.  
Even videos with a frame size of 720x576.

Could someone please explain to me how to achieve a aspect ratio setting of 
square with dvd::rip?  Or a way to postprocess the file under Linux so that 
the aspect ratio is set to square?


Thanks and regards,
Horst
