Pro Tools "h/w Buffer Size" Options

[theunderground]

Every once and a while in Pro Tools LE I get this message:

Audio processing is conflicting
with other CPU tasks. If this
occurs often, reducing the "H/W
Buffer Size" in the Playback
Engine Dialog may help
prevent the problem. (-9129)

I do as I am instructed, then I try pressing play and this message pops up:

The operating system held off
interrupts for too long. If this
occurs often try increason the
"H/W Buffer Size" in the
Playback Engine Dialog.
(-9094)

so I switch back the buffer size to 1024, and that usually takes care of the problem, but every once and a while it doesnt, and I get a nasty cycle between these two messages.

Im running Pro Tools LE 6.2.2 on a dual 1.8 G5 (512MB RAM) using it with Reason Adapted. This hasn't been a huge problem, but I am considering using my M-box for live shows, and that would be really bad if does that in the middle of a song. The only solution I can think of would be getting more RAM, but 512MB seems like a reasonable amount, and I am usually only working with, at tops, seven tracks.

any help is appreciated

Not using any fiber in's, but I do have an ATTO ultrawide SCSI card installed in my sawtooth 400 G4. Although this is a qualified card with digi, do you think it would still be possible for it to interfere with hardware communications? In a similar situation, I installed an Encore 1.2 GHz G4 processor upgrade and had problems even starting up my mac. The guys at sonnet said some SCSI cards aren't compatible with their upgrade cards, but I took the damn thing out and tried the processor upgrade again and no such luck. It forces me to believe my next move may be my best move...upgrade to the new and upcoming G5 (when it eventually comes out) and the digi002r.
