[MPlayer-users] mencoder/xvid: issues with forced PAR using a DXN profile

[Daniel Klaffenbach]

Hi,

I am trying to convert some DVDs for my hardware DivX-Players using mencoder. 
I'm using the "profile=dxnhtpal" option to make sure that the files can be 
played back on my devices.

I noticed a little problem with this setting though: when encoding videos the 
PAR gets forced to 0/0:
"xvid: par=0/0 (vga11) forced by choosing a DXN profile"

This leads to problems on my devices concerning the aspect ratio of the 
encoded movie. Mplayer plays the encoded file with the correct aspect ratio, 
but neither VLC, nor my hardware DivX-Players use the correct aspect ratio.

I already experimented with some xvidopts (autoaspect and aspect ) and with 
force-avi-aspect but this did not change anything. I tracked the problem down 
to the PAR being forced to 0/0.

Without forcing the PAR to 0/0 (which means without using a DXN profile), the 
files play correctly on all of my players (VLC, Panasonic hw player, Philips hw 
player, Panasonic TV).

Is there any reason why the PAR is forced to 0/0 with a DXN profile? Could this 
possibly be prevented with a xvidopt?
