Things are really not reliable yet. In particular it does not work at all to play songs from smartlists for me. I try to use the default pick 100 songs smartlist and the songs will not play. Also picking music directly is hit or miss. All my music is WM lossless format and so is getting converted on the fly. Here is some of the debug log. If you need more of it let me know and I will email it...
