Ok, I may not know my terminology. How I have PP set up is on the top half of settings under Renderes I select my Office MC as the Renderer. On the bottom half of settings under Serverss I select my Office MC as the server. I assume at this point since I am not selecting PP as the renderer it is the control point. I do not see a selection for PP as the server which would be cool in some respects but I really am not loading music on the iPhone anyway to avoid using iTunes but I do have some test music on it but I still do not see PP as a Server in the server list. When I have it set up this way is when I can play only one song at a time. I can advance to the next song in the playlist when the song ends or by selecting next track but I have to manually initiate it to play.
Ok, you are using MC as the renderer AND the server. In that way you are using PP as a fancy remote (I use it that way too).
PP isn't a server, it would be more complete if it could do that but it might be a hassle for the developers to get at the itunes DB (just to find the music) or perhaps they could do it differently and it's not a priority for them yet.
I don't get why yours is stopping at the end of each song. I can't get mine to do that. On the playlist screen in PP, do you have an arrow going from left to right near the bottom between playlists and edit?? That's the thing that tells it to go on to the next song. You can tap it and cycle through the choices.
This is the same way I set it up with my XBMC on my XBOX but I select it as the Renderer and my Office MC as the server. I can try to not use the same instance of MC for both the Server and Render. I never really thought of that. I have 4 other PCs running it so I will try that tonight and see if this is just related to using the same instance of MC as both the Render and Server.
It absolutely should work with MC in one instance, that's how I use it at home!
What version are you using??
