Before going to sleep yesterday evening I programmed about 80 tracks in the Tidal playlist (mplayer, lossless, USB). So if everyting was ok it should still have been playing this morning. But this morning the BDP1 was not playing and again in a kind of pause position, and I had to reboot it to become responsive again. So 2015-2-26 is a big step forward, but there's still some work to do. I'll keep you informed if I'm able to pinpoint 'the problem' to specific actions.
