A way to perhaps get more debug info, would be to kill off the player after booting, and then rerun it with strace:

rwm
strace -f player &> /drive0/log
rom

Then post the /drive0/log file here as an attachment.

In case you don't already have strace, I'm attaching it again to this post. Put it onto your empeg, mark it as executable, and give the full pathname for it in the above command.

Cheers
