This morning I went back through my notes I kept during beta testing of the Conductor. I remembered I had a problem where one of the songs I picked at random to test the MP3 player would not play it. It would play just fine with any other media player, e.g. Real Player or Windows Media Player, but it would not play on the Conductor. In my case I found a space/blank character in the middle of the name. I don't see that in your case from the Mediainfo though. The only other time I had an issue was where the MP3 file was corrupt and it wouldn't play on anything.
The files names look OK (8 characters or less).
I assume that the song will play OK on another media player, e.g. Real Player or Windows Media Player, correct?
The mediainfo for the songs looks good . I think a sampling rate of 44 KHz is recommended but 48.0 is OK.
You might try recreating the MP3 file with Audacity and see if that makes a difference. It appears to me to be an issue with the MP3 file.
I'm not sure what I meant by question # 5 so ignore it although the comment about switching modem ports bothers me.
