I have a new 2007 R-320 which has the MB factory RES DVD monitors behind the front headrests. So far it will only play DVD format movies but none of my DVD-R disks format!

The Command Owner's Manual (page 88 and 89) stated that the player should be able to play all formats: DVD-R, DVD-RW, DVD+R, DVD+RW. The manual stated that the factory setting is on Regional 1 for US, but can be reset for other Regions by MB service centers. I called my MB service advisor and he is waiting for answers from MB tech specialist.

Anyone has the headrest RES and is able to play DVD-R or DVD+R formats?

Thanks for any good suggestions.
