I have tried my jukebox with WMP 11.0 at work and a friend also tried my application on his Vista machine (which comes with WMP-v11.0 installed) and it seems the jukebox application does not play MPG files for some reason.
I need to look into this ...... just letting people know to stick with WMP9.0 or 10.0 in the meantime
Well, I just upgraded a computer at my house to Windows Media Player 11.0 and my application works find. I needed to install the appropriate codecs for the videos I wanted to play, but that is just normal WMP setup.
Anyway, I believe the computers which had problems on it before simply did not have the correct codecs loaded......
