maybe it was this?

Also make sure that AE is properly interpreting the field order and pixel aspect of your source file. If you click on the source in the project window, the information displayed at the top of the bin, should say something like “separating upper field”.
If it doesn’t, right click on the footage and choose “interpret” and change the settings. AE needs to know the field order and pixel aspect of the source footage to correctly display and work with the footage.

You might also consider purchasing the DVCproHD decoder from DVFilm. This will add the ability to read those Quicktime DVCProHD files on your Windows machine. Might save you a lot of time.

They also have an encoder/decoder package available:

There are several reasons for not working in HDV. Since HDV is MPEG-2 it is compressed using intraframe compression, meaning that not every frame of video is a full frame of video, rather some are full frames followed by frames that only include changes that have occurred. During the decoding (playback) process these partial frames refer to the full frames (I-frames) to then display a complete frame of video. This decoding process is more taxing on the computer since it has to do a lot of overhead processing to create frames of video in order to display and work with them.
When you convert the footage to a lossless codec, you are decoding this compressed video once and creating full frames of video for every frame. The file size of the video will be much much larger, but it will be easier to work with and not cause the system to do additional processing.

A white screen is usually indicative that your system is missing the proper codec to properly play the file. Since your second system doesn’t have FCP installed it is probably missing the codec that FCP used when you captured the footage.

It is best when working with HDV footage and AE to convert the footage into a lossless format. HDV uses “long GOP” MPEG-2 compression which can be difficult to work with efficiently in AE.

actor filmed in front of a green screen (the background is one of their products). Then they rotoscoped the head out using a simple animated mask (notice the deep v-shape in the front where his chin was).
The “plasma” bolt and the smoke are probably also elements from their products.

nevermind…re-reading your post I see you’ve already seen that.
Here is some info on the Gworld
https://en.wikipedia.org/wiki/QuickDraw

I recently built a pretty complex comp in AE using very huge solids in “3d” space, a bunch of lights and a camera. Occasionally, I would get similar errors (I’m using a PC, so no gworld)…however, I found by using lower quality and magnification settings as well as the draft 3d, I was able to work better.
Since the error seems to be related to graphics rendering and memory, maybe something similar might help.

A quick search of the net brought up this from someone that had the same problem. Might be helpful…

“NM folks…i changed the colorspace under project settings, and it seemed to have fixed…i have no idea why. maybe it was trying to sparse the preview thumbnails in a weird color mode that was throwing an error….oh well hopefully others can learn from my mistake”

What is your end result deliverable? What do you plan on doing with your rendered file? DVD? web? back into an NLE?

The reason it might look strange when exported with a non-square pixel aspect like 1.2 for widescreen, is that some players like Quicktime do not properly compensate for non-square pixels, showing the video as square pixels, which looks distorted.
If you plan on compressing this for the web or for primarily computer playback, you can use your encoding software to adjust and compensate stretching the image out to using square pixels.
With material destined for DVD, also uses your encoding software to add the 16×9 flag when compressing to MPEG-2 so that once authored onto a DVD, the DVD player will stretch the anamorphic widescreen image out and either letterbox/pan&scan for 4×3 sets or display it properly on a 16×9 set.

I use On2’s Flix8 Exporter, which will give you an option in AE under “export” to export to FLV or SWF. From there you can adjust the size (or use current comp size), bitrate, vbr/cbr, 1/2 pass, framerate, etc… I’ve been using it for years and it produces great results.

Yes. AE 6.5 can import and manipulate HD footage. Keep in mind that AE is a compositing application and not an editor. You will drive yourself mad if you attempt to do any extensive editing in it….that’s what editing applications are for.
