Has anyone tried the Archos PMA430 with video input/encoding and video 
out in a loop for EyeTap type applications? Is it fast enough to get low 
latency video input back out to the VGA *and* do archiving/encoding to 
disk at the same time? Is there any CPU left over during this process (I 
know it has dedicated MPEG encoding hardware DSP, but if the video 
caputure buffer and disk management takes all the CPU due to bad 
software design you still can't do much else for lack of cycles).

The more hard data the better, like cpu load during the video in, 
capture, out routine.

Thanks,
-chris
