Lr 3.4.1, moovies, and nas-volume

Question

a small bug-report:
i have a network storage for my pictures, and inside the are a few quicktime-moovies. Trying to import this network volume to Lightroom 3.4.1 showed me, that moovies cannot be imported. The pictures itself imported in a reasonable amount of time, but as soon as there are moovies inside the nas-volumes, it worked and worked and worked, overnight, the next day. No progress visible.
I created a new catalog, moved the moovies from nas to local hard disk, and imported the nas-volume again. Success, in a few hours all was imported.
Then i imported the moovies from local hard disk. Again success, worked fine within a few minutes. The last thing i had to do is to tell Lightroom the new (ahem, old) storage place for the moovies.
Is there any tricky workaround that can import moovies direct from a nas volume?

LR 3.4.1 may write keywords differently than previous versions due to fixing an error with corrupting metadata so there could be a bug particular to LR 3.4.1, but Adobe needs to be able to repeat it with a simple example in their facilities or hear enough reports of it that they feel there is an issue and they can find a problem with their code.  From what you've said (except the unexplained situation about how it didn't work to move the file from your USB to your C drive) everything points to your USB drive having an issue, though.
Adobe would likely want to do a remote troubleshooting session on your computer unless they've already diagnosed the issue on another computer.  You might try posting your issue on the more official "Feedback" forum that Adobe seems to look at more:

but be ready for the same skepticism and litany of questions that you've gotten here. 
The intermittency is your biggest issue to getting anything resolved.  A reason for intermittency could be a timing problem where some other process like a virus-scanner, or a media-scanner, or some other thread in LR, itself, like the preview-generating thread, is accessing your image at the point that LR is trying to write the keywords to the image file, or the fact that the image is in disk cache or not, where a USB-drive would have less cache than an internal drive and access is generally much slower via USB than internal IDE or SATA drives.
As a way to see if it happens on more than just your particular USB drive, try everything on a memory-card in a card-reader to simulate a USB-drive.  If you can get that to work then there's a little more hope in someone else repeating it.  Be prepared to give a step-by-step procedure from virgin-JPG prior to import up until the error-message is received with specific keywords and keystrokes used to get the error.  Be prepared to provide an example JPG, too.
