Great! That's what I thought.

That's the problem... we're long on memory and short on CPU with the 
patch I'm working on. I hoped I could use [pix_buffer] to get some of 
that CPU back at the expense of a lot of RAM...

Besides, I couldn't preload *all* my clips with the 'ram' message 
anyways. Only the one I'm currently playing. My patch has 48 clips which 
will be addressed by three different players, so a way of storing all 
the vids ahead of time is required to avoid lagtime starting the video 
when it's requested.
