@LukeI know you are busy, and I really do appreciate the time you have given me. I have spent a great deal of time trying to figure out why the Emby server doesn't fetch the next channel in your "virtualTVexample code. When a program is selected to play (by clicking it in the EPG) it always starts at the beginning. It's interesting that the duration timer at the bottom of the Emby client shows the correct playing time. Also, when the program ends (and again when the duration timer ends) the following error is thrown.

From my novice knowledge I assume that this error was caused by the server failing to find the next program to play. To remedy the problem the server fetches channels again. I am sure the server is doing this because it believes it's out of channel data.

@Luke Can I modify the "Ensure Channel Schedule" code in the "VirtualTvExample" so it will provide to Emby the next program to play. For example, as a temporary fix, can I reload the channel data at the proper point to start playing the next program and then tell Emby to start playing it? If this idea is worthless, please give me some pointers on what I can do.

Any success I have, I will share with @pünktchenand he is always welcome to use freely any of my code in any way that he chooses.

No, this comes from the EPG. It will just start playing the channel at the current time, meaning whatever is currently on the channel.

@Luke I discovered this a short while earlier today.

Is the problem in the server code? I ask this because the error log says the server was not able to find the next program to play.

Should I abandon this project? Will a fix be available anytime soon?

Where does it say that?

@Luke I read it in the Emby log. I will try and recreate the event and send you the log. I have been watching via log messages each time the server calls anything in the Tuner code trying to understand why the next channel is found OK in Chrom but not with Android. Sometimes even Edge goes to the next program OK. As a temporary fix I was considering sending a playlist to the client when a program is requested. I know @pünktchenhas this working. I am only interested in this solution for my own use. Do you have any ballpark idea when this problem will be solved?

@LukeWhile waiting for the problems associated with playing programs in the virtualTvExample code, I decided to try a simple work around. One similar to what @pünktchenis doing. In the GetChannelStreamMediaSources task I added a small program that builds a playlist from the schedule info and then I send that playlist to the client with a "Play Now" command. I have tested this idea and it works. I have experienced one strange problem when clicking a movie to be played. The client plays the playlist OK, but it adds trailers for the movies to the front of the playlist. TV shows are played OK. All of the code is below. Now programs start at the proper time and programs in the schedule play sequentially.

Do you have any suggestions on how to improve this idea? Of course, when the changes for the virtualTvCode is ready I will remove this code.
