Public bug reported:
When showing videos using gstreamer, e.g:
gst-launch-0.10 playbin uri=file:///path/to/video
The aspect ratio is calculated incorrectly (it looks like it is half the
width it should be)
Changing my xorg.conf to disable TwinView:
< Option "TwinView" "0"
< # Option "metamodes" "CRT: 1600x1200 +0+0, DFP:
nvidia-auto-select +0+0; CRT: 1280x1024 +0+0, DFP: nvidia-auto-select +1280+0;
CRT: 1024x768 +0+0, DFP: nvidia-auto-select +1024+0; CRT: 800x600 +0+0, DFP:
nvidia-auto-select +800+0; CRT: 640x480 +0+0, DFP: nvidia-auto-select +640+0"

> Option "TwinView" "1"

> +0+0; CRT: 1280x1024 +0+0, DFP: nvidia-auto-select +1280+0; CRT: 1024x768

> nvidia-auto-select +800+0; CRT: 640x480 +0+0, DFP: nvidia-auto-select +640+0"
Fixes the problem.
(I don't really understand how TwinView works, but the metamodes line looked
like it was related, so it got commented out).
The video card is a GeForce 6600, using the restricted driver
(v1.0-9639) (as installed by the restricted manager)
