I have no idea. I'm not a techie... To make the whole thing more understandable (if you did'nt read my first reply):

It's when I have listned to a file, and then shut down panucci, and start it again. The time is correct, but when I press play, it makes a jump.

All files have been ripped from cd by me on the same computer with the same program, and then merged into one big file by me in the same program, so nothing there.
