Scaling Issues When Rendering

I'm sure I'm doing something very basic wrong, but I need new eyes.
I've got a project edited in Adobe Premiere Pro, shot in 16:9 (1440 x 1080). I'm pretty sure I've set it to export at those ratios, which I then import into EffectsLab. I do this by opening a blank timeline and setting the ratios manually. They I render it back to AVI, again using those same ratios so I can re-add it back to my Adobe project.
That's when things go wrong. The rendered AVI is scaled wrong, and doesn't fit the Adobe project's size. As in, it looks like picture-in-picture when I add it to a secondary video track. It's always smaller.

When you render back to AVI, are you using any compression?
The reason I ask is because I had a similar (but not identical) situation where rendering with no compression would squash my video and add black bars to the top and bottom (with all of the correct project settings), but if I used DirectShow for rendering the same project with no other changes, it would render with the correct ratio.
Mine, however, would look ok when I imported back into Vegas, but it just seems a bit odd to me that I had a ratio issue when using AVI and now to hear something similar.

I've tried a few compressions, and the results vary, but the aspect ratios still don't match. Of course, it doesn't help that EffectsLab keeps crashing on me...

If it keeps crashing, check that you have the latest version of EffectsLab
installed and that your computer meets the minimum system requirements
(I'm assuming that it does).
If you do have the latest version, try a clean reinstall

In what way is it smaller? Is it along the sides, the top, or both? Is the aspect ratio still correct, or is everything squeezed horizontally?

It's both a smaller image entirely AND squashed a bit (to varying degrees) vertically.

Does it look right inside EffectsLab? Does it actually fill the canvas frame properly?
What specific project settings are you using?
What specific render settings and compression settings are you using?
There's no logical reason for this to be happening, unles at some point along the workflow there's a settings glitch.

This is a long shot, but I ran into something a little different than what I mentioned earlier in this thread.
The issue I mentioned above happened with 4:3 video (although it turned out not to really be an issue since everything looked good once I brought it back into Vegas. It just looked squashed in Windows Media Player after being rendered in EffectsLab, but was fine once brought back into the Vegas timeline).
However, I've since run into an issue when rendering widescreen footage. If I render as widescreen in Vegas, and then import into EffectsLab (this happens in the CompositeLab demo that I'm playing around with, too) using the correct widescreen settings, everything looks good in EffectsLab and CompositeLab on the canvas while I'm adding effects and compositing. When I render any widescreen project in either of those programs, the video file that is created is squashed horizontally and has black bars on both the left and right side (which is just the opposite of how it appeared with my 4:3 videos). However, when I bring this video file back into Vegas, it does not look like it should the way my 4:3 video did once brought back into Vegas. It looks just horizontally squashed and has black bars on the side. So, if I then render in Vegas, my rendered file retains the horizontal squashing that I had after rendering in EffectsLab.
I did finally figure out how to correct this, though, at least with Sony Vegas. Apparently the lab programs are somehow changing the aspect ratio flag when I render. Here is what I'm seeing from beginning to end:
The clip that I render in Vegas before taking it to EffectsLab or CompositeLab has the following settings:
Pixel Aspect Ratio: 1.2121
When I bring that file into EffectsLab or CompositeLab, I verify that it the project settings are 720x480, NTSC Widescreen, and 1.2 for the aspect ratio, and that "assume project is widescreen" is checked in preferences.
Once I render, as I said before, my image is squashed horizontally. I import the EffectsLab altered file back into Vegas, and it still shows as squashed. What I finally figure out is that if I right-click on my video file on the timeline within Vegas, the Pixel Aspect Ratio now shows as 0.9091 instead of 1.2121. I'm not sure why this is because I've made sure that all settings remained as they should throughout the process, but I've repeated this process at least 3 times now that I figured this out, and every single time when I render in a Lab product, I end up with a video that has the correct resolution, but an aspect ratio of 0.9091.
Luckily, in Vegas I can just change the Pixel Aspect Ratio setting from the video clip properties on the timeline using a drop down menu that has the correct setting. This makes everything appear as it should in Vegas, and my final render looks like it should.
Sorry if this is a little confusing and long winded, and I don't know if Premier has a similar option to change the aspect ratio back on the individual clip files once re-imported, but I thought I'd mention it as this helped me and it may be worth looking into.

alienux: I tried a few tricks like that, and it didn't help, I'm afraid.
No, it doesn't look right inside EffectsLab. It doesn't actually fill the canvas frame properly. It's distorted as I described earlier.
The settings in Adobe (and for the export to Quicktime) are: 1080X1440, 25 fps, HD Animorphic 1.333
The render settings are Single file, DirectShow (.avi). I've tried a few compression settings, and this is (I suspect) where I'm going wrong. Right now it's on "Animation" in AP, "Microsoft 1" in EL.
I agree there's no logical reason for this to be happening, and at some point along the workflow there's a settings glitch. Problem is, I have no idea where or what. Break it to me gently: I'm and idiot, and what I'm doing wrong is...

If you are importing a Quicktime file into EffectsLab, I'd start by switching your render settings to match, and rendering from Quicktime to the QT Animation codec as well.
Also, if you can open the file exported from Premiere in Quicktime, then select Window > Show Info or Show Movie Inspector, depending on your version of Quicktime, and check the resolution of the file before it enters EffectsLab.
