Most of my clips are XviD or Divx and they are failing miserably. Mind you, these were playing just fine with FW 2.10. I have AVCHD clips that have heavier bitrates, but this box doesn't even support them.
As someone else said in another thread, "I've never had to strain myself with any other product this much"!! Enough of sleepless nights with this so called "DLNA supported box". I'm throwing this in the trash & buying QNAP shortly.
