After I update my XBMC (I've deleted old version under /xbmc, /TDATA/0face008, and /UDATA/0face008/), the new XBMC can't play any RM or RMVB files. There is no reponse after I choose those files. I've tried many versions (0521,0527,0531, etc), but none of them can play RM/RMVB on my xbox. Although the original version can play it, there was a lot of noise while playing it!!
