I need to play 6 clips of video in the meantime, i have success with pdp_qt but it goes nasty on the hd.
I have better result with pdp_fqt which load data in memory before play, but it get all the process in loading and freeze all while it load.
I wonder if there is a way to make the loading the lowest priority possible ?

SCSI disks for use with pdp_qt? Or perhaps even firewire drives - that standard is meant to offer the same advantages of highspeed async IO (depending on how the particular drivers work I guess).

With pdp_fqt - does enabling threads help at all? possibly not... unless DSP is already running.

Maybe stream media from another machine, though that's getting very elaborate & startup could still be slow..
