On my Mac I have no problems similar to what you are describing.
For anyone to respond you need to provide LOTS more information on ...computer stats / clip properties / sequence settings / playback resolution in Program monitor/ raid array configuration...
In Premiere Pro I am not aware of any way to de-chipmunk media running at 2x or more.

Having the detail as Tom mentioned would help people help you easier- but have you upgraded to 5.5.1? They improved H.264 scrubbing quite a bit with that update. Also, I have the same request as you do about the 2X shuttling - much better on FCP at this point - and the only thing you can do is join in with a feature request for the next version.
Use Shift+L multiple times to increase playback incrementally (I think 25% each time) which will give you much smoother audio playback.
No need to request it--it's already there.
Here are my computers specs:
2.66 GHz Intel Core i5 (iMac) (Quad core)
8GB 1067 MHz DDR3
I've tried this on many different types of footage, mostly using Proress or native 5D files. My playback resolution is set to 1/4. I'm using Gtech 7200 hard drives with Firewire800.
I just updated to 5.5.1 and I noticed a tiny improvement. I have Final Cut open and I'm comparing how it srubs versus Premiere and there is a DRASTIC difference. I'm running an old version, FCP6, and its drastically faster in scrubbing than Premiere.
Using Shift+L doesn't fix what I'm talking about. Its still changes the pitch of the audio. Final Cut Pro doesn't change the pitch of the audio when you play back video, no matter how fast you play it back. Its a HUGE help when editing interviews, you can edit in double playback and still understand what's being said, big time saver. Looks like you can't do that with premiere unfortunately.
Funny; I use this all the time in Premiere Pro with no issues. Since most of my editing is interviews, I'm using it frequently and am still able to get things done.
Your machine *may* be a little underpowered - H.264 decoding is pretty CPU intensive. I am running a MacPro 8-Core with 32GB RAM, footage on a RAID, CUDA-enabled card and I still have issues at times with H.264 decoding. Also, it has been my experience that dropping the resolution on H.264 to half or a quarter sometimes makes the CPUs work extra hard vs. playing back full-res. Can you take a look at what your CPUs are doing while playing and scrubbing in the activity monitor?
It shouldn't be happening with ProRes, though... hm...
Also, again, I share your frustration with the 2x audio. Sure you can do it incrementally, but the pitch-shift is still there. Chalk at least one win up for FCP at the moment.
As an experiment, you may want to try copying one of your AVCHD files to a local drive & seeing how it performs there. You might be experiencing a combination of not enough CPU + i/o contention with the firewire drives...
But yeah, in general, Pro Res will decode easier than AVCHD. The fast scrubbing is the tradeoff from FCP forcing you to transcode all your footage up front.
Hi guys, not sure if are aware of this thread,
But I've found that scrubbung h264 DSLR footage was smooth as butter, but in CS5.5 it's very choppy.
This is what I found on my win7, cor3 i7 3.2, 24gb RAM system.
Hopefully adobe with fix this with an update soon
