This sounds a lot like the video setup that was at LCA 2005.

Alas, the only thing I was able to find was a Blog post by Mikal
bemoaning that all the MPEG streams were corrupt.

Asides from the SNAFU, it seemed to work quite well, there was a number
of displays out in the foyer screening sessions in progress, including
mapping all of them onto a rotating cube effect.

P.S. While we're on the topic, someone suggested GeexBox to me as a media player
solution, and I'm very impressed with what a 6Mb PXE boot image can achieve. :o)

Has anybody tried this?

My group is trying to decide between using a bunch of small MPEG decoder boxes to display composite video on a TV or decoding the MPEG streams on a computer and displaying the results on a monitor. The same for audio.

We don't have the space for multiple systems. So we're thinking about trying to run two dual-head video cards on a single system for video and multiple sound cards.

It seems to me that X-Windows and ALSA should handle this sensibly. But, as always, the devil is likely to be in the details. Has anyone actually tried doing anything like this? Any recommendations, horror stories or other experiences that we can draw upon?
