New problem

Some of films don’t have a thumb, the system downloads all the film data except for the thumb of the cover art. It’s sort of annoying.

Any suggestions?

Check to see if it created a zero-length cover file, if so, just delete it and rescan for content info.

Ummm, in English?

If only “some” of your films don’t have a thumb … why not just manually get one ?  (eg.Google Images)

grab a medium sized one eg. 300x450 or less

and rename it exactly the same as your video file (with a *.jpg extension of course)
