Ambarella may have worked out a kludge where the AC3 can just be passed unprocessed through to the computer along with the h.264 encoded video. Then it becomes the computer's job (driver? ArcSoft capture module?) to figure out that it's AC3 rather than AAC or PCM and handle it properly. Since nobody at Hauppauge knows much about video and audio processing they're having trouble figuring out how to handle this (at best it's been given to some junior programmer while senior level programmers work on something else). Or they're waiting for Ambarella and/or ArcSoft to figure it out.

If that's the case, I, the_tom, rebkell or several others could come up with a solution REALLY quick if they gave us the chance.
