Hey all,

In particular Chris & Jamie,

I'm working on an installation that plays 16 256x192 photo-jpeg videos.
The patch works fine to start, but slowly and surely the video play-back
gets worse and worse, getting choppy and dropping frames. Eventually the
video playback looks like 1frame each second or so (after 1hr or so of
running) and I'm not sure how to fix it.

According to the activity monitor I'm reading 8 to 15MB/s from the disk,
so I thought I would try spreading the content over two disks, but that
seems to have made little difference, or it just takes longer for the
playback to suck.

top and the activity monitor say PD is using 98-120% CPU usage, but
according to the CPU monitor, looks like both CPUs are sitting around 85%.
PD is using 100MB of RAM, and 380 or so of virtual memory. I am not seeing
the RAM increase to indicate a leak...

When I first load the patch the CPU usage stays the same, the RAM usage
starts at about 70MB, and the Virtual memory at 350MB. The Disk IO is the
same as well. So I don't see anything in activity monitor, or TOP that
reflects the fact that the video playback gets terrible after an hour or
so.

I'm right now using the pixelTANGO installer, I'm trying the extended
releases now, which show the same consumption of resources, but I'll have
to wait an hour to see if the end result is the same.

Any suggestions so I can figure out what is going on?

Oh and this is on a dual 2GHz G5 with 2GB RAM.

Thanks
