[Jason Johnson] “There is just a blank spot on the preview window and the timeline is empty. The layer shows something is there but I can’t see it on timeline or preview window.”
Try selecting the layer and pressing the ‘[‘ key. This should move the in point of the layer to the location of your current time indicator on the timeline.
If you see something in the timeline then you may need to extend the in or out points so that you can see the entire clip.
There are several reasons this may be happening but they all relate to the placeholder layer having a different duration/in point than the footage you are replacing it with.

AE and Premiere are both tools for producing videos. So they could definitely figure into producing interactive videos, but they would allow you to produce the “video” while the “interactive” portion would have to be handled by some other authoring application.
What you’ve described, for example, sounds a lot like a DVD menu system. You could use a DVD authoring package to create interactive videos, but they’d then need to be played back through some software/hardware that plays DVDs.
You could also add interactivity using Flash.
Ultimately you could even create the rudimentary interactivity you’ve described using Powerpoint.

I’m not familiar with combined ATI + NVIDIA setups. Everything that AE is reporting looks ok though. I’m afraid I don’t have any other ideas. Do regular 3D solid layers show up?

The Reshape effect with some tweaking of the paths may work. It’ll get more complicated if the layers are continuously rasterized.

Here’s an old post that includes an example file. This is set up with expressions and gives a pretty convincing volumetric light/projector effect:

I just realized I indicated that you select the footage in the timeline, what I meant was the project panel. Apologies for confusing things further 🙂

You might be able to do this with an expression. You’d create a single comp with all 600 images in it. Trim those layers to 1 frame and use Animation > Keyframe Assistant > Sequence Layers… to put a different image on each frame. In the parent comp you’d apply Time Remapping to each instance of this pre-comp and apply an expression there.

[Nathan Rice] “I have played 100+GB lossless files before without a problem, and these are just little 10 sec. clips.”
The size of the file isn’t a good indicator of playback performance. The data rate is more important. A 10 second 6GB file is more likely to stutter than a 3 minute 100GB file. In addition the data rate of the Animation codec can be variable within a single file as it uses run line encoding to compress data.
That mumbo jumbo aside you should trust the RAM preview in AE over the playback of the file in another application. If that’s stuttering you might want to check for frame rate mismatches between the comp and the footage.

Your description of the situation is confusing.
If you have missing footage you should select it in the timeline and use cmd-opt-h (mac) or ctrl-h (pc) to relink it (replace the placeholder of the missing footage with the proper footage).
If you could describe what you are trying to achieve in more detail then maybe someone could give you another option.

If you are animating the camera then you don’t need a null.
If you are animating the objects then you could either:
1) Animate one of the layers and parent the other two layers to it.
2) Animate a null and parent all 3 layers to it.
In general I would pre-compose the frame layer with its content, then you only have 2 layers to deal with.
Alternatively you could parent the frame layer to the layer it’s framing (or vice versa). In that case you don’t need to parent the child layer to the null since the parent layer would already be parented to the null.
