Quicktime squishes to 4:3 after Motion parameters changed

Question

I videoed something using two DV camcorders simultaneously and both were set to 16:9.
I captured the two lots of footage having specified DV-PAL Anamorphic in Easy Setup.
I synchronized the footage on V1 and V2 and, using "Image+Wirefire", I manipulated the corners to show both on the Canvas.
I then chopped out bits here and there in V2 to show the event from different angles as it proceeded.
To review what I had done I exported to Quicktime and all looked fine - two small 16:9 windows, V1 showing continuously and V2 appearing and disappearing exactly as hoped for.
Next step was to resize the video images back to full screen. I doubled clicked a clip, clicked on the Motion tab, clicked on the red cross opposite 'Basic Motion' which set the scale back to 100 and the Center to 0 and 0.
(At this point I would have used Paste Attributes to promulgate the new attributes to other clips but for the purposes of this question I currently only have two short clips on my Timeline)
For the next review I once more exported to Quicktime and to my consternation I see that the whole little movie has been squished to 4:3 format.
I checked the Aspect Ratio under Distort and that remains as 0 both before and after clicking on the red cross mentioned above.
Instead of pressing the red cross I have also tried changing the Basic Motion Scale to 100 and Center to 0, 0 by hand but the subsequent Quicktime movie gives the same squished result.
I have the same problem with AVCHD footage that I have used Log and Transfer to acquire.
Is this a bug? Is there a setting in Quicktime that I've not come across?
If you have time then could you too try putting a short clip on V1 and on V2 and trying it. And please let me know if you get the same result..? It's all very worrying as I do a lot of multi-camcorder stuff.
Many thanks in advance for any help.

Answer 1

Thanks for that Tom. I was thinking of iDVD but from what you say it looks like I should be looking for an alternative. Is there another product that is recommended around here? I'd be most interested in knowing about it. Something that maybe takes the MOV file, allows me to specify animated menu buttons, has a reasonable range of modifiable menu templates, is of reasonable cost and maintains a good level of image quality?
I'm very new to FCE but I'm already much enjoying the easier way of editing multitrack video and stability by comparison with Premiere Elements.
I very much appreciate your advice and the superb support that is so apparent round here.
