Looks like it's complaining about the headers on the MP3 file (see text at bottom of screen).

1) Check out your copies of the files and see if they need repair. Links to relevant software are in the FAQ.

2) If the files play OK on other players, even if they do have some kind of error, save copies of the bad files anyway to send to the empeg guys so that they can make their new decoder work with them.

3) Is the player UI completely locked up requiring a reboot? If so, that's probably a bug for the empeg guys (having it lock up in info:transient like that).

4) Can you reproduce it without Mlord's kernel? You need to make sure that's not a factor.
