Why Does PE12 Misplace Added Overlay?

Question

The project is pro-bono for the University of Maine's Surveying Engineering Technologies department and the Screencast-O-Matic clip fills up most of the frame with a much smaller picture-in-picture clip of the instructor should any of that matter. The Version PE12.0 (20130903.main.557123) project is being worked on a Windows 7 Pro 64-bit system.
The problem is this: The added smaller overlay clip of the instructor is placed on top of the larger screen captured video clip. Registration looks fine in PE12's 'Monitor' but after rendering (now three times!) that overlay clip has been shifted.
In particular, the original raw clips (both at 1920 x 1080) that are being worked with come from two sources:
Canon EOS 5dM3; .mov; H.264;  29.97 fps
Screencast-O-Matic; .avi; MP42; 10 fps - also its MP4 rendered version.
In the screen capture above as seen in Windows Media Player (VLC shows similarly) with the overlay clip having slid to the right and well beyond the rightmost limits of the frame.
In the screen capture below as seen in the PE12 'Monitor', the clip is properly placed left of the rightmost limits of the frame.
The well documented (http://forums.adobe.com/message/5770383) problems besetting PE10 and NVIDIA drivers; and moreover, Adobe's and NVIDIA's refusal to address them, forced me to purchase the upgrade to PE12. Thankfully those problems linked with PE10 are not present with PE12; however, it seems that there are new issues plaguing PE... including the program crashing within the first 60 seconds, and the eternity it takes to load an existing project.
In PE, I've tried various approaches in setting the New Project's project settings; e.g.,
DSLR 1080p DSLR 1080p30
DSLR 1080p DSLR 1080p30 @ 29.97
PE12 output rendering thus far has been limited to 1920x1080 in .wmv format (as requested by the University)
After the first disappointment, I checked for a PE12 update, and after its installation and rebooting the computer, have tried rendering out of PE12 twice more, both unsuccessfully and with identical results.
Thank you for any replies.
