I had this same problem - I have a US model of the H320 - You have to update the firmware, but the US model only got to 1.04 and it sucks - go to

download the KOREAN version 1.31 version - it supports the US model. Once youupdate the firme ware on your H320, you will have to go the the main menu and switch the language to english. Once I did this the DRM problem dissappeared.
