Video playlist not working

Hello, I have a serviio running in my home server. I connected with xbmc "client" and made playlist as follows:
#EXTM3U
#EXTINF:0,smesh_S02_E001.mp4
upnp://66b17924-a918-30c6-825f-637d4ad1 ... 10%24MI89/
....
and next 20 items same format. I've uploaded it to my DLNA server where all my media is stored. After rescan servii did found new playlist.m3u file. But I can't see any new items when running xbmc and go to the video->playlist.

What is the common procedure of generation video playlists?

The playlist creator I use has the option for M3U and PLS formats. I use PLS, and the format looks like this:

  Code:

[playlist]
File1=J:\All This, and Heaven Too (1940).mkv
Title1= -  - ALL THIS AND HEAVEN TOO
Length1=8601
File2=J:\Casablanca (1942).mpg
Title2= -  -
Length2=6150
File3=I:\Citizen Kane (1941).mkv
Title3= -  - CITIZEN KANE
Length3=7167
File4=J:\Deception (1946).mkv
Title4= -  - DECEPTION
Length4=6720
...

I tried using the M3U format, but had greater success with PLS.

I'm not 100% sure, but it could be the file hasn't gathered metadata, and Serviio is ignoring the videos. I know if I have a file that Serviio can't find any online metadata, the file doesn't appear in my lists. The only place I believe they appear is in the Folders listing.

Thank you for the answer. While I trying to create playlist myself without any software in text format you provided (with no success unfortunately), could you please kindly describe full procedure of playlist creation (how you did it), including your hardware configuration and software used. Many-many thx in advance!

EDIT:
By some reason the .pls playlist have appeared, so it seems I'm on the right way!
