Serviio and XBMC: stack movies

Hello,
I use XBMC and Serviio for trascoding (using .nfo XBMC's files). But I have a problem: some movies is composed from many files like "Avatar - CD1.avi" and "Avatar - CD2.avi".
XBMC collapses stack movies and show only "Avatar.avi". When I play the movie XBMC shows "Avatar - CD1.avi" and after "Avatar - CD2.avi" without user interaction.
Servviio shows both "Avatar - CD1.avi" and "Avatar - CD2.avi".
It is possible collaps stack movies in Serviio?

It's not possible.

It's not possible.

So, Serviio can't manage file list showed through uPNP?

it can, but it doesn't know the 2 files are related - therefore doesn't stack them.

What then is the proper way to handle these files? I mean file/folder setup and naming? Or where should i post this question if this is not the proper place?

Thx

I keep them with the same name, they appear with the same title in Movies folder but ordered properly.

Thanx thats what i have done
