error quicktime -2048

I have no idea what a -2048 error is...as far as I can tell it's not an Apple error...May be a server error.

I would suggest not to up-load directly from your camera to a server.

-2048 error means no movie found. If the file wasn't closed correctly you would get this error.
Nothing QuickTime can do to fix it and you may want to check with the manufacturer:

Ok I'm stumped...Is this an encoding error?

Don't think so. I think the camera probably just records for a predetermined period of time or is continuously recording and then uploading "chunks" of data to the server.
If these chunks were extracted and then not re-saved as a new file they may have been corrupted.
Probably QuickTime is not seeing the "end" of the file from these chunks. Think like you did a cut in QuickTime Pro. If you didn't paste that into a new file and just sent it to a new location it could get corrupted.
That camera uses a wireless network and if it isn't fast enough data could also be lost making the file incomplete. Those same files could possibly be opened in other players that are less strict than QuickTime. VLC and Real Player are two I would try.

Your probably right. All I could fine was, Qt on a server, camera error, encoding error, audio error...

Must be transfer errors... meaning not seeing the end of the file.

-2048 is a QuickTime error dialog. A user would also get this error if they were attempting to open a MPEG-2 file without the needed component installed.
