I think I had that, make sure PP isnt running and you close all the Adobe Processes in task manager.

If anyone is having problems I've added a few cards into my text file and attached it. Just save it to the directory below and overwrite your file in there.

c:\Program Files\Adobe\Adobe Premiere Pro CS5\

Great - Thanks - it works - IT is Fantastic how premiere handel video now - Cant wait to start editing projects in CS5....

Please let us know the results MPE vs Software as I'm about to purchase a GTX 470 tomorrow and would be keen to know your thoughts.

Dont have much time testing today but 1 hour and 6 minutes DVCPro HD exported to quicktime DV took 12 minuttes with hardware activated and 21 minuttes with "only software" Tried editing with more layers with colourcorrection and other accelerated effects and no accelerated effects - and no lost frames (hardware)

What power supply are you using Bo?

I'll beat Bo on this, I've got Antec Earthwatts 500; I thought it will not be enough but it's running smooth and stable.
A note about noise/heat. the GPU runs at 80c most of the time, and the fan noise doesn't really become audible until 56%, anything below this setting it's quiet.

Yeah all the reports say a min of 550w and 38amps on the 12volt line

Keep in mind that is the minimum requirement. If you are running a bunch of other devices, multiple HDs or optical drives, they all draw power. I personally went with a 900watt power supply to be safe.

550W PSU is sufficient if you do not install hard disks, DVD/BR burner and use only one stick of memory and do not overclock your system, do not use USB ports, etc., and do not plan to use it longer than one year.

If that is not the case do not consider anything below 750 W.

Look here, and calculate with a 100% load and 30% capacitor aging, then add around 15% to the estimated wattage: eXtreme Outer Vision - eXtreme tools for computer enthusiasts

I am in the process of building a new dual boot box (Mac + Windows) -w- a GTX 285 and I went with a 1200 watt BFG power supply.

I have an 1000 watt corsair with mountable power cables. I made it a kind of standard in my computers as I often put a lot of cards, fans and harddrives in it too. Dont want to go down on the power side as it is not expensive. Again Thanks Adobe.....

Martin, I can confirm at least the GTX280 rocks and rolls with this hack. Just playing with the CS5 trial version and I'm sold!

Hackintosh
 

It works on my hackintosh with GTX 275 1792 MB ram. I did the same way windows users did.

perfectly working with my good old GTX260 (192sp, 896MB memory). i was even able to flawlessly edit xdcam video in fullhd on dual core cpu. had to upgrade to quad anyways. damned AVCHD...
OT: is anyone else having trouble playing same AVCHD clip in two layers above, top resized to be smaller? it works fine if its two different clips, if the same clips are in the same position, but once you move the so they are not in sync, it wont play more than few frames, cpu load is not reaching 100% by far. hope its just a bug
