As far as I know, digikam will only read metadata from XMP sidecar files with 
extension .xmp. 

You can specify other sidecar extensions, which will ensure (on paper) that 
such sidecars are copied and moved with the image or video files. As stated in 
the settings dialog, such files are never read from, nor written to.

Which makes me wonder why you are sure that digikam's import dialog read the 
.thm? Afaik, .mpg files can also contain at least basic metadata, the .thm 
mostly provides a thumbnail for quick access.
