I've been seeing the same for a few weeks now. It is occasionaly preceeded by "Hiccups", then it locks dead. The graphics keep turning, though.
I have been keeping Mike posted about this, but at the moment it's rather difficult to track.
Listen out for hiccups; if it does lock up,
don't pull the unit straight away - rather, wait a few minutes to see if it recovers. It has recovered once on me (6 hangs since 1.01) and once I have been able to get it to change sources to the radio, and then back to the player whereupon it kept going without a hitch. Report what you see to bugs@empeg.com.
