Are you referring to the Playlist slots in the Connections menu ?
There are two lines seen when you open an m3u Playlist slot
1. Playlist URL
2. Playlist VOD URL
Is that what you are referring to ?
With the papiao m3u Playlists, the VODs are included with the original Playlist.
So you should be able to open the VOD selections thru that first line without needing to add a second.
Use the RCU's VOD button to bring them up (I think).
You could mess around with this thou and add the same URL to the second line as what you have in the first line, maybe.
Then open the connection and see what kind of results you get.
Use the RCU's VOD button maybe.
I say 'maybe' because I never tested this particular feature
In that menu, you can see a file folder type icon shown directly after each line. That opens up your USB storage and will show any hardcopy of a m3u Playlist you may have on that storage device. Its a fast way to enter the correct path.
As far as entering the Playlist URL, that needs to be done by typing it in... or if you are gonna mess around with all this and do not want to keep typing that long, long URL onto the line, then you can copy and paste the URL addy by using Total Commander (file manager).
The link below is from the Dreamlik T3 tutorials but it will be exact same for the Z8... only thing different is maybe the Total Commander is not in the Z8 Market . But you could find the apk version of it and load it manually.
