Roger, similar % of usage on my machine also. I have Vista x64 SP2, Quad Core 2.83ghz.
CS4 4.1

I am getting in 92% range when viewing in high quality playback and 75% range if previewed in Draft mode

O.k, then i am not alone with this issue. I see the same issue on my old laptop as well.

I updated the graphic card driver and that helped a bit, but not much. It is ImporterProcessServer.exe that uses all that power when i playback the footage. This Process belongs to Pr CS4.

CS4 was a standard install on a clean version of Vista x64 to the Program Files (x86) on the C drive.

full file path Adobe/Common/Plug-ins/CS4

I am somewhat remote on a satelite link and keep loosing your server. I had not finished this responce when this last happened.

The full Premier path is Vista/Program Files (x86)/Adobe/Adobe Premier Pro CS4

I notice that CF filters installed in Adobe Premier Pro CS4/Plug-ins/common and also put a Cineform folder into the Adobe/Common/Plug-ins/CS4.
The files all have the same date so I presume they all installed at the same time.

They work when moved down one level to Adobe/Common/Plug-ins/CS4/Mediacore

Is the Vista part of "Vista/Program Files (x86)/Adobe/Adobe Premier Pro CS4" really in your path. Please should the full path including the drive letter, as that path looks weird.

Vista is the C drive that machine is dual boot and I tend to use the labels and ignore the letters. It should be:

C/Program Files (x86)/Adobe/Adobe Premier Pro CS4

I am getting ImporterProcessServer.exe crashes quite regulary and it blames the cineform dll. :-)

I tried, but it requires a serial number and i have a trial verison of Neo Scene.

However, playback 1920x1080 CFHD footage in Pr CS4.1 and take a look at the CPU usage and how much of that CPU usage ImporterProcessServer.exe uses. I see the same issue on any CFHD 1920x1080 Timeline and/or directly in the Source which rule out any mismatch between media and Timeline.

Hey Islandman, how's the bleeding edge? You back to CS3 for serious work? Just wondering if the bloodpressure level in the Islands is going up again...or if your CS4 projects are actually limping forward? (come on, admit it, that CS3 workstation behind you is still doing the real work)

No, that is not snickers in the background...I really feel for you...

I guess Adobe is getting like MS with their version numbers: "anything odd is good, even is not".

Maybe CS5 will chase the 4 blues away...if there's any blood left in us. Maybe we'll get lucky and Google will come up with a cloud computing editor to take on Adobe...snick snick...

At the moment I feel like Adobe has their head in the clouds and I have a fully fledged "cloud editor".

I still remember all the screaming about how crappy CS3 was compared to PPro2. So a bit of revisionist history here, I think...

Stephen:
I am actually moving along rather smartly on a 30 min program (200-300 clips in the bins) using PHD4/CS4/Firstlight. It's all running pretty smooth. The power of i7/ Vista 64/ Big RAM is very impressive and I do like PPro CS4. So far, no lock ups, crashes, etc. Occasional minor previewing problems due to lack of CF RT playback, but no big deal so far. I'm encouraged!!
And...duh...I did finally find my Mediacore folder- everything seems to have installed in the right folders.
I'm finding Firstlight to be both terrific and convenient as a basic CC/Clip Tweaking device.
Bottom line: right this minute, CF/CS4 seems to be working better than CF/CS3 does on the old XP/Quad system.
We may finally be coming down the home stretch on all of this.

Well, smack my mouth! That's the best news I've heard all day! And yes, I confess, now that I remember back Adam...CS3 was crap city in the beginning. Maybe there is hope for CS4 after all?

I'll have to turn my chair around and go back to bleeding with CS4 on another workstation for a while, and see if you guys are telling me the truth...ha!

I sure hope so, we've got lots of work ahead and we need all the POWER we can get.

Keep bleeding! Keep bleeding! We need the fixes and you guys have got my attention now...

Interesting because I always liked CS3. I started out with PP2 also. CS4 is the FIRST TIME that Adobe reminded me of Microsoft which is not good.

But looks like Cineform is fixing all the Adobe errors which is great to hear.

hmmm
 

Booya...fixed :)
