I just found a solution to the jumpy playback problem!!! I went to Network in System Preferences and turned off my airport, and now everything plays smoothly! I do not know why this works. I never had to do this before. As an additional test, I turned the air port back on and clips were jittery again. I have agonized over this problem for more than a month, and am happy to find a simple solution!

I still have not been able to find any solution to the jumpy, jittery playback of my HDV clips in FCP. I posted the problem on several forums and found at least one other person with the same problem, but still no solutions. I had given up on finding a solution, but I will take one more stab at it this week when I go into Apple for a One to One session. I did not specifically download any new Codecs, but I have consistently done all software updates, and I am wondering if something in one of those changed my system so that I no longer have smooth HDV playback. As I said before, my playback was great up until a few months ago.

My internal and external hard drives are both in good shape. I did use Disk Utility and all is well. My clips are on the external drive. I just copied a jumpy clip to the internal hard drive and I still have the same problem with playback there. At the Apple Store, we also tried putting problem clips on several of their computers and still had jumpy playback. Since the original footage is fine and the output is fine, it really seems like a problem with the way QT is dealing with the HDV footage, but if I am the only one having this problem, then maybe that is not it either. The other factor pointing to QT is that fact that clips in past projects are now jumpy when they were not before, but if there is something else causing the problem and someone has a quick fix, I will be very happy.

If you are asking about the HDV camera that I film with, it is working fine. I originally thought the camera might be the problem, but tests have revealed that it is fine.

I just now tried your suggestion, and it did not help. I also played around with other combinations of settings with no luck. Thanks for the suggestion though.

Ok, here is my last post on this subject. I played around with FCP and discovered that when converting HDV to DV in FCP, if you get a jumpy image, you can apply a Shift Fields filter and that corrects the problem.

I will try a comparison using HDV and Pro Res for rendering.
My final SD DVDs look pretty good on a standard TV, and not so good on an HDTV, so maybe I am just hoping to get a SD DVD picture quality on my HDTV that is not possible using software encoding.

I just tried converting an HDV sequence in FCP to a DV sequence, and it looks jumpy, so maybe you are better off capturing the squished DV image that the camera creates.
I have been doing my editing in HDV. Then I take my edited sequences back out to HDV tape and the image quality is great on all TVs, standard and HD. For the SD video, I have been going to Compressor then to DVD Studio Pro. Image quality with this method is good on a standard TV, but simply ok on a large LCD HDTV.

My HDV is interlaced.

I have no problems controlling my HC7 with FCP 6.0.2.
First of all, I prefer to capture in the HDV format. If you let the camera covert to DV, it squeezes and distorts your image to make it fit in a DV screen.
To capture in the HDV mode, use the touch screen on your camera and go to the Standard Set. Find the iLink Conv and set it to OFF. In FCP, go to Easy Set Up and choose HDV1080i60. Set your camera to the PLAY/EDIT mode and you should be able to control it with FCP. You can edit in HDV, then convert to SD in FCP. This will give you a undistorted widescreen image with black lines at the top and bottom.
If you still want to let your camera do the converting, Go to the Standard Set. Set iLink Conv to HDV-DV. Then in FCP, go to Easy Set Up and choose DV-NTSC.
