Arch Linux

Description:
I have a firewire camera (Imagingsource DFK 41BF02.h) and I am using Coriander to get images (video) from the camera. The issue is that on the video buffer seems to get played twice. That is, whatever happens in front of the camera is shown twice. The period of repetition depends on the size of the 'DMA ring buffer' which I can set in Coriander.

I'm not sure that its the kernel which is at fault, but I think I have eliminated the possibility of any relevant package being the culprit.

From my understanding, Coriander is basically a front end for the libdc1394 library which depends on libraw1394. The issue doesn't seem to be with Coriander, as an application which was developed in house has the same issue when built and run on my machine. If I boot into Ubuntu 12.04 on another partition, the camera works as it should in both Coriander and our application. That version of ubuntu seems to be using a slightly older version of the libdc1394 and libraw1394. However, I have tried downgrading these packages in Arch and compiling them from the latest source and the issue has persisted. I have also tried using Coriander 2.0.1-1 from the AUR and compiling 2.0.2 from the source.

Additional info:
* package version(s) tried:
linux 3.9.7-1
libdc1394 2.2.1-1, 2.1.3-2, (and 2.2.1 from source)
libraw1394 2.1.0-1, 2.0.5-1, (and 2.0.5 from source)
Coriander 2.0.1-1 (AUR), and 2.0.2 from source

Steps to reproduce:
Install libraw1394 and Coriander and make sure you have 'video' group permissions.
Plug in firewire (non DV) camera.
Launch Coriander and click on 'display' in the 'services' tab.
Display window should now repeat every X number of frames, where X is the DMA ring buffer size set in the 'capture options'
