When I run xine or mplayer to play Mission imposable 3 (which is an anamorphic widescreen DVD) they detect the aspect ratio as (3) 16:9 which is correct. When the DVD is played it appears as if it is displayed 3:1 stretched horizontally and very narrow. When I run xine with -apsect anamorphic and mplayer with --aspect 4:3 the video is displayed correctly.

Are there any configuration options that would allow anamorphic videos to automatically display correctly? Could this be a bug/feature in one of the libraries they use?

libdvdcss-1.2.9
libdvdread-0.9.7
libdvdnav from CVS
MPlayer dev-SVN-r22005-4.1.2 with xvmc support
Xine-lib 1.3.3 run with xxmc

This is probably a problem with Xorg. Check for an incorrect DisplaySize setting in your xorg.conf. Your monitor may also be sending the wrong value. What aspect is your display?

Its a 16:9 display which in my xorg.conf under monitor I use DisplaySize 240 135.

After testing af few things I found that it was not just my HDTV that had this behaviour. This happens on my computer monitors (4:3) as well.

my mplayer.conf
vo=xvmc
vc=ffmpeg12mc
ao=alsa:device=hw=1,2
ac=hwac3,hwdts,a52

When I execute '#mplayer -aspect 4:3 dvdnav://' the output is perfect
'mplayer -aspect 16:9 dvdnav://' produces very long squished output.
I have even tried setting -monitoraspect 16:9 with no luck.

Are you correctly using a 16x9 modeline like 1280x720, 1224x688, etc or are you using a 4x3 modeline like 1024:768 or 800x600?

If you're using xorg, these need to be in your xorg.conf:
Option "useEdidDpi" "FALSE"
Option "DPI" "100 x 100" in the

If your display is 16:9 but its native resolution is not 16x9, I believe you have to play with the DPI setting above.

Sorry, those should be in the monitor section. Give that a try and report back.

The screens native resolution is 16:9.

Option "useEdidDpi" "FALSE" << This is a subset of IgnoreEdid and could not be added

I have added this Option "DPI" "100 x 100"
There is no change in bahavior
