REally? This wasn't at all the case with the Sony EX1, express card and usb gave vastly different off load times, are the Sony compatible cards just faster?

Get CS4, and an nVidia CUDA-enabled graphics card (the more powerful the better), and you should get realtime performance from the 7D files.

SxS and regular Compact Flash are engineered differently. SxS transfers at up to 100 MB/s (800 Mbps). That's way more than what USB 2.0 can do (480 Mbps). However, even the best of the best CF cards right now, i.e. the SanDisk Extreme IV, only does 45 MB/s (less than 400 Mbps).
I didn't with CS4.1 on a Core2 Duo T7700 @ 2.40GHz running Vista 64. I can't even play NeoScene converted AVIs smoothly from the timeline. The GPU is a Cuda compatible NVIDIA too. I am running everything from the same c:\ drive though...w8ing on the 7200rpm Firewire 800 external to get here with fingers crossed for just a little bit of joy.

Hard drive won't make a difference. It's probably because your CPU is a mobile chip rather than a desktop one.
Portability and mobility is a huge part of the 7D draw for me. I insist on a laptop based editing solution...even if it means i7 next month. I feel absolutely ripped off that NeoScene won't play smoothly from the timeline though. The clip window plays the NeoScene AVIs as smooth as glass...just falls to choppy jerky hell when you drag the clip onto the timeline and try to play it. VERY frustrating...I hope it's something stoopid I'm doing.

Do the files play smoothly in QuickTime, outside of Premiere?
BTW, the reason why I say that the hard drive won't make a difference is because Premiere (or any application, really) isn't "run off of the hard drive" in the strictest sense. When applications are launched and active, they run from the RAM. Barry or Eddy or anyone else familiar with programming should be able confirm this.

Since you're running Windows, you shouldn't use QuickTime to play AVIs. QuickTime wasn't really designed for that.
Video codecs for Windows typically use DirectShow, which is part of DirectX. QuickTime might not be using DirectShow/DirectX properly, which could explain why it's not playing your CineForm AVIs. In fact, I believe that on Windows, you have to install plug-ins for QuickTime in order to get to play things like DivX/XviD, even when you have those codecs (for Windows) installed.

Mine is a mobile chip, a Core 2 Duo at 2.4GHz in a laptop. But with an nVidia Quadro NVS 140M (lower-end quadro card) and it can play 720p clips full-screen and 1080/24p clips full-screen (can't handle full 1080/60i clips though).
Realtime playback through nero or on the timeline in CS4.1.

BTW, that pretty much proves that it's not a hard drive issue.

mhood's problem might have to do with how Premiere is rendering the clips on the timeline... Sorry if I'm stating the obvious...
Not totally smoothly. It's close when reduced to half size but no cigar.
It doesn't help that my old D90's AVIs play as smooth as glass on everything (including QT). I even edit my D90 footage on an old Pentium 4 at 2.66GHz with 640 MB RAM and an old copy of Premiere Pro 1.0. It's as smooth as glass...

But the D90 uses MJPG, an intraframe codec. Infinitely easier on the system than a long-GoP like the h.264 the 7D uses. So, frankly, I'm not surprised you have much better performance from D90 files, that is perfectly to be expected.

You must have; I tink that 570M would smoke my NVS 140M, so you should easily be getting fullscreen realtime playback.
Try downloading a trial of Nero and see if it can play the files back fullscreen in realtime. If it can, your hardware is up to the task, and you must just have some setting off in Premiere. Oh, and make absolutely sure you have the 4.1 update, not 4.01, of CS4. The acceleration came about in 4.1 IINM.

I'm on XP, not on Vista, so maybe there's something to that?

Perhaps. Vista's performance has been demonstrated to be slower than XP's. But Windows 7 has been shown to be faster than XP, overall.
