Video Database - Multipart / Video files stacking (1 Viewer)

[Der_Bub]

Hello,
for Importing new Multipart Films to videodatabase, I have renamed the files as described in wiki:

Example:

Herr der Ringe Die Gefährten (2001) [tt0120737] CD1.mkv
Herr der Ringe Die Gefährten (2001) [tt0120737] CD2.mkv

But after Import only one part (2nd File) is imported.

How can this be solved? What can I do to Import the files to one Film?

Thanks!
