AVGeek - do you have yours resuming even if power is cut while it's playing? Mine will resume if I exit out of MPXPlay and THEN power down, only. Is there some special setting to get MPXPlay to (constantly) write the current position in a song such that if the power is cut it still knows where it last was?
I have tried both powering down and exiting directly. Both times it has jumped back to the last position it was playing at. What switches are you using to launch mpxplay? I wrote a batch file that I run with my autoexec.bat. I set up a playlist file for all of my music that the batch file refers to.
