Yes, that's a good idea. It's not implemented in MPExtended at the moment, but it shouldn't be too hard. I think we've actually planned it for 0.6. Meanwhile, if you've some development experience you can implement it yourself (it shouldn't be too hard), or you can create the playlist file manually. If you download the playlist file for a few channels, concatenate them together and make the continuationId parameter the same for each link (doesn't matter which value), I think it should work out-of-the-box.
Uh yeah, that's quite a tedious task. Somehow I thought you were talking about only TV channels. I'm afraid there's no way to do that automatically yet.So...i am definitely not a developer, but i am a little familiar with how m3u playlists work. how can i get everything in one playlist short of downloading every m3u link and adding it to the rest? over 1100 movies and more then 6K episodes...i'll die before i finish! i am sure you told me something that i did not understand, perhaps you could point it out for me? thanks a lot for the help.
