i noticed that in this emu even with the samsung the cdrs or cdrws dont run as well as the hd i got this problem with 1 skip like every 20 seconds......this only happenes to some games and this is even though my samsung plays xbox games perfectly on cdrs rws. If it comes down to using the hd or a cdrw/cdr disc, choose the hd if you have the space. Your games will run lot smoother. i really didnt notice a difference in these two releases in terms of playability but there are a lot of new features. another great release by the way keep up the good work xport!
