Thanks for your reply Slim Shady,
The session I am running is less than 10 tracks with minimal edits. i have a gig of Ram in the machine, and have allocated 230meg to ProTools and 240Mb to DAE (leaving the minumum setting at that, as Digi recommends). Also I do have a handshake scenario going on with the SPDIF device. I usually leave it set to internal but, tried this b/c everytime I go to hardware setup or playback engine the problem stops and playback resumes, for a little while and locks up again. I also downloaded the Apple PCI extension that Digi released for dual processor machines, but that was not the fix. Tried everything in the past 48 hours with no resolution. could it be a hardware problem? Digitest passes the card. I am at a lost. My last resort is to reformat the machine, but if anyone has seen this problem before and has a resolution for it, please help.

Thanks in advance,
Dan Cheung
