In regards to your space bar delay - is it doing it on unrendered footage? Or is it doing on any footage, with or without effects added?

Steve,

I completely agree, staggered spin-up is great to implement, it will put less burden on the PSU, but anything after that related to power saving should be turned off on an editing machine, just like screen savers or sleep/ hibernation modes.

Ha- finaly found the settings in WIN7 for the harddisks - The power saving options only let me choose between "Turn of Screen" and "turn into sllep mode". Advanced setting let me choose the Sleep Hardisk setting - it was set to 20 min. just about the time where I have problems if I let my computer be untouched. Editing now, but I let you know it it was the problem for me...

Yes - it was just the harddisks going to windows sleep.............................. My problem solved...

It was doing it on a single layer of .AVI with no effects. But for me it seems to be random. Sometimes it plays immediately when I hit the space bar, sometimes there's a delay. I can't figure it out.

I swapped out the WD caviar drives for my old Seagates (my previous RAID 0), and the random delay is still there, although my drive disappearing seems to be fixed.

Drew, try 2 things:

1) Do what Bo did and turn off the power saving features. easiest way to find it is going thru the screen saver settings - there is a 'change power savings' button.

2) Open up Task Manager, then hit the space bar in Premiere and see how high the CPU usage goes. I have noticed with CS5 that the CPU always spikes upon initial playback and then settles down.

3) Is there any delay when you click the "Play" button in the Program window?

have the same problems myself...
anyone found any solutions?

Re: PP CS5: space bar delayed response?
 

I have suffered with this too from when I installed cs5.5.

i7960
24GB
Win7 64x

O\S: Intel 160gb SSD
Cache & Previews & Page File: 3TB (1.5x2) RAID 0 7200rpm
Media & Project: WD Black 2tb

I have the same issue when my Media & Project was on a Segate RAID 0 too.
